PO Box 4501, Radstock, BA3 9AS is a genuine high-volume postal address in Radstock, Somerset, but the PO Box alone does not reliably identify the organisation that sent a particular letter.
It appears to function as a bulk-mail or return-address facility used in connection with correspondence sent for different organisations.
There is a strong reason why the address is associated with commercial mail processing. CFH Docmail operates a major print, post and hybrid-mail business from St Peter’s Park, Wells Road, Radstock, BA3 3UP.
Official corporate records show CFH Docmail Ltd as an active company involved in printing, licensed postal carriage, software and data processing.
However, current Docmail support information names a different PO Box — PO Box 1933, Radstock, BA3 4YF — as its standard return address.
This means it is safer to describe PO Box 4501 as a valid high-volume correspondence address rather than claiming that every letter displaying it was sent directly by CFH.
If you have received a letter showing PO Box 4501 Radstock BA3 9AS, the organisation named inside the letter is more important than the return address printed on the envelope.
What Is PO Box 4501 Radstock BA3 9AS?
The address is:
PO Box 4501
Radstock
BA3 9AS
United Kingdom
BA3 9AS is a valid Radstock postcode associated with a single PO Box address and is classified in postcode datasets as a large-user postcode.
Large-user postcodes are commonly associated with organisations or postal-processing arrangements receiving higher volumes of correspondence than a normal household or small office.
That makes PO Box 4501 different from an ordinary street address.
| Detail | Information |
| Address | PO Box 4501, Radstock |
| Postcode | BA3 9AS |
| Postal area | BA |
| Town | Radstock |
| Local authority | Bath and North East Somerset |
| Address type | PO Box |
| Postcode use | High-volume/large-user postal address |
| Customer-facing office | No evidence that it is a walk-in office |
A similar distinction applies to other bulk-mail return addresses, where the PO Box can identify the organisation handling correspondence without necessarily identifying the business that created the letter.
Who Is Connected to the Radstock Mail-Processing Operation?
CFH Docmail Ltd has a substantial documented presence in Radstock.
The official Companies House record lists:
| Corporate detail | Current record |
| Company | CFH DOCMAIL LTD |
| Company number | 01716891 |
| Status | Active |
| Incorporated | 21 April 1983 |
| Registered office | St Peter’s Park, Wells Road, Radstock, Bath, Somerset, BA3 3UP |
| Printing SIC code | 18129 |
| Licensed carriers SIC code | 53201 |
| Data processing/hosting | 63110 |
The company’s activities therefore closely match the type of infrastructure required for high-volume business correspondence.
What the Corporate Record Actually Confirms?
The Companies House information is useful because it independently confirms who CFH Docmail Ltd is, where its registered office is located and the categories of business activity recorded for the company.
What the corporate register does not do is identify every PO Box or postal-routing address used within the company’s mailing operations.
It is important, therefore, to distinguish the physical CFH facility at BA3 3UP from PO Box 4501 at BA3 9AS. Current public corporate records confirm the physical site but do not explicitly state that CFH exclusively owns PO Box 4501.
Why Might a Letter Show a Radstock PO Box Instead of the Sender’s Office?
Large organisations frequently outsource printing and posting.
A bank, council, healthcare body, housing organisation or other company may create the underlying communication but send its data electronically to a specialist mailing provider.
The mailing provider then produces the physical letter, inserts it into an envelope and passes it into the postal network.
The process can look like this:
Organisation → Print and mail provider → Postal network → Recipient
The envelope’s return address may therefore belong to a postal-processing system rather than the organisation whose name appears on the letter.
This explains why someone in Manchester, London, Birmingham or another part of the UK could receive correspondence carrying a Radstock return address even though the organisation contacting them has no office in Somerset.
The same principle can apply to a customer correspondence address, where the postal destination and the organisation’s physical headquarters are not necessarily the same place.
The Sender and Mailing Provider Are Different Roles
This distinction is particularly important when deciding whether an unexpected letter is legitimate.
The sender is normally the organisation responsible for the content, account or decision described in the letter.
The mailing provider may simply process the electronic document, print it, put it into an envelope and arrange delivery.
In a hybrid-mail arrangement, the organisation creating the correspondence can remain responsible for the customer relationship and underlying records even though another business physically produces and dispatches the letter.
A return address should therefore not automatically be interpreted as the headquarters of the bank, NHS organisation, council or business named inside.
Why Is CFH Docmail Relevant to High-Volume Mail in Radstock?
CFH operates hybrid-mail and managed-communications services from its Radstock base.
The government’s Postal Services & Solutions framework includes CFH Docmail as a supplier under the hybrid mail, digital and transformational services lot.
The supplier information records the same St Peter’s Park, Wells Road address and company details.
CFH’s published case studies also demonstrate that its services are used for significant volumes of communications across sectors such as healthcare, local government, finance, pensions, housing and private business.
What the Government Procurement Record Proves?
The public-sector framework is useful evidence because it confirms that CFH has been listed to provide hybrid-mail and related communication services to public bodies.
That supports the wider explanation of why correspondence created by an organisation elsewhere in Britain could be printed and processed in Radstock.
However, procurement approval relates to the supplier and its services. It does not independently establish that PO Box 4501, BA3 9AS is an exclusive CFH postal address.
This helps explain why recipients may encounter a Radstock postal-processing address on correspondence originating from an organisation elsewhere in the country.
It does not, however, prove that every envelope carrying PO Box 4501 was produced by the same company.
Does PO Box 4501 Tell You Who Sent the Letter?
Not necessarily.
The return address provides information about where undeliverable correspondence may be routed, but it may reveal very little about the organisation responsible for the content.
To identify the sender, examine the document itself for:
- The organisation’s full legal or trading name.
- Company or charity number.
- Customer or account reference.
- Telephone number.
- Official website.
- The purpose of the communication.
- Payment or response instructions.
- Privacy information or regulatory details.
A letter showing PO Box 4501 could therefore relate to different types of communication.
The address should not be used on its own to conclude that the sender is a particular council, bank, healthcare organisation or private company.
Is PO Box 4501 Radstock BA3 9AS a Scam Address?
There is no basis for saying that the PO Box itself is a scam address.
It is a real postal address.
What matters is whether the particular communication using it is genuine.
A legitimate mailing facility can process genuine communications for many organisations, while an unexpected letter still needs to be assessed according to its own contents.
| Sign | What it could mean |
| Recognised organisation named inside | Potentially genuine |
| Account/reference you recognise | Supports legitimacy |
| Letter relates to an expected service | Usually reassuring |
| Unexpected payment demand | Requires verification |
| Pressure to pay immediately | Check independently |
| Request for passwords or PINs | Major warning sign |
| Strange web address | Do not follow without checking |
| Poor spelling or inconsistent branding | Reason for additional caution |
This is similar to situations involving another high-volume PO Box: the address alone may not establish who sent the correspondence.
How Should You Verify a Letter From PO Box 4501?
If the letter concerns something important, verify the organisation independently.
Do not start by using an unfamiliar telephone number, QR code or website printed in an unexpected letter if you are uncertain about its authenticity.
Instead, find the organisation’s official contact details independently and ask whether it sent the communication.
For example, if the letter claims to come from a bank, use the number on the back of your bank card or the bank’s official website.
If it claims to come from a council, use the contact details published on the council’s official website.
If it concerns an NHS appointment, contact the relevant clinic, GP surgery or NHS organisation through a contact route you already trust.
Details Worth Comparing
When checking a letter, compare the name, account reference, dates, amounts, company number and contact information with records you already hold.
It can also be useful to check whether the organisation recognises the reference number and whether the reason for writing matches an account, appointment or service you actually use.
If several details match an existing account or service, that can provide stronger evidence than the return address alone.
If nothing in the communication is familiar, avoid sharing financial or identity information until the sender has been confirmed.
What Happens When Mail Is Returned to the Radstock Processing Facility?
Specialist mailing platforms can offer different ways of handling undelivered post.
Current Docmail returned-mail guidance describes three broad options.
| Return option | What happens |
| Not managed | Undeliverable mail returns to the processing site and is securely destroyed |
| Managed returns | The reason for return is recorded against the client’s account before secure disposal |
| Client’s own return address | The undelivered letter is sent directly to the client’s nominated address |
Return Information Can Flow Back to the Original Sender
For managed returns, reasons may include addressee unknown, gone away, incomplete address or refused delivery.
That information can be useful to the organisation that originally supplied the mailing data. It can show that a customer, patient or account holder may no longer be reachable at the address held on file.
The mailing client can then use the return information to identify incorrect records and update its own customer database.
This process is more sophisticated than leaving returned letters sitting indefinitely in an ordinary PO Box.
Does Returning a Letter Stop Future Mail?
Not automatically.
Returning correspondence can alert a sender or its mailing provider that delivery was unsuccessful, but it does not necessarily remove your address from the original organisation’s records.
If mail repeatedly arrives for someone who no longer lives at the address, it can help to mark the envelope clearly as:
“Return to sender – not known at this address.”
However, where possible, contacting the organisation named inside the correspondence may resolve the issue more quickly.
The original organisation is ultimately responsible for maintaining the customer, patient or account information that caused the mailing to be generated.
Why Does Secure Data Handling Matter?
Large-scale mailing providers can process substantial amounts of personal information.
Depending on the client, documents can contain names, addresses, financial information, healthcare communications, pension information or other confidential material.
CFH states that its operations hold security certifications including:
- ISO 27001 for information security.
- Cyber Essentials.
- Cyber Essentials Plus.
- Relevant data-security controls for healthcare communications.
Its public-sector supplier listing also confirms that the company provides hybrid-mail services through a government procurement framework.
Sensitive Information During Hybrid-Mail Processing
Hybrid mail involves more than physically posting an envelope. Information normally has to move from the organisation creating the letter into a system capable of producing the printed document.
That makes access control, secure data transfer, production controls and appropriate disposal important parts of the process, particularly where correspondence contains health, financial or other personal information.
These controls are relevant because hybrid-mail providers receive electronic customer information before turning it into physical correspondence.
They do not, however, establish that every communication using a Radstock PO Box is genuine. The contents of the individual letter still need to be verified.
Can Healthcare and Council Letters Come Through a Commercial Mailing Provider?
Yes.
Public bodies do not necessarily print every letter inside their own offices.
Outsourced and hybrid-mail services can be used to send high-volume communications such as appointment letters, notifications, statements, billing documents and service updates.
CFH publicly documents work involving healthcare organisations, councils, pension administration and other public-sector bodies.
A recipient should therefore not assume that a letter claiming to come from an NHS organisation or council is fake simply because the envelope has a Radstock return address.
Equally, the Radstock address alone does not prove that the letter is genuine.
The sender named inside should still be independently verified when the communication is unexpected.
Is PO Box 4501 the Same as CFH’s Registered Office?
No.
The addresses are different.
| Address | Role |
| PO Box 4501, Radstock, BA3 9AS | High-volume PO Box/return address |
| St Peter’s Park, Wells Road, Radstock, BA3 3UP | CFH Docmail registered and operating address |
| PO Box 1933, Radstock, BA3 4YF | Current Docmail default return address identified in official support guidance |
Three Addresses With Different Functions
The difference between these addresses is important.
St Peter’s Park, BA3 3UP is the physical registered and operating address confirmed through corporate records.
PO Box 1933, BA3 4YF is identified in current Docmail support material as its default returned-mail address.
PO Box 4501, BA3 9AS is a separate large-user PO Box address. The official records reviewed do not establish that it should automatically be treated as identical to either of the other two addresses.
This distinction is one of the most useful facts for anyone researching the keyword.
A PO Box is a postal-routing address. It should not automatically be treated as a company’s registered office or a premises customers can visit.
How Can You Contact the Radstock Mailing Operation?
CFH’s published contact details for its Radstock head office are:
| Contact method | Details |
| Head office telephone | 01761 416311 |
| Docmail customer support | 01761 409701 |
| General email | info@cfh.com |
| Support email | customersupport@cfh.com |
| Physical office | St Peter’s Park, Wells Road, Radstock, BA3 3UP |
These contact details relate to CFH’s confirmed Radstock operation.
If your question concerns the contents of a particular letter rather than the mailing process itself, contacting the organisation named in the letter will normally be more appropriate.
What Should You Do After Receiving Unexpected Mail From PO Box 4501?
Receiving an unfamiliar letter does not mean something is wrong.
Start by opening and reading the correspondence carefully rather than judging it from the return address alone.
Then establish:
- Who claims to have sent it.
- Why that organisation would have your address.
- Whether the account, appointment or reference is familiar.
- Whether the contact details match official records.
- Whether money or sensitive information is being requested.
- Whether the deadline or request is reasonable.
If the communication can be confirmed independently, the Radstock PO Box is unlikely to be important to the recipient.
If the sender cannot be verified, do not make payments or disclose sensitive information simply because the letter looks professionally printed.
Conclusion
PO Box 4501 Radstock BA3 9AS is a real high-volume postal address, but it should not be treated as proof that one specific company sent every letter displaying it.
CFH Docmail has a confirmed large-scale printing and hybrid-mail operation in Radstock at St Peter’s Park, and official government procurement records show it provides hybrid-mail services to public-sector customers.
However, current Docmail guidance identifies PO Box 1933, BA3 4YF as its default returns address. Current official sources do not clearly establish PO Box 4501 as CFH’s exclusive current PO Box.
The best way to identify a letter is therefore to check the organisation named inside the correspondence, verify its details independently and treat the PO Box primarily as a postal-routing or return address.
Frequently Asked Questions
Who uses PO Box 4501 Radstock BA3 9AS?
The address is used for high-volume correspondence, but current official records do not conclusively identify one organisation as its exclusive user. Check the company named inside your particular letter.
Is PO Box 4501 Radstock legitimate?
Yes, PO Box 4501, Radstock, BA3 9AS is a valid postal address. That does not automatically verify the contents of every letter displaying it.
Is PO Box 4501 owned by CFH Docmail?
CFH has a confirmed major mail-processing operation in Radstock, but its current official help centre identifies PO Box 1933, BA3 4YF as the standard Docmail return address. Public official records reviewed do not directly confirm exclusive ownership of PO Box 4501.
Why have I received a letter with a Radstock return address?
The organisation contacting you may use an outsourced printing or hybrid-mail provider. This can result in a Radstock return address appearing even when the sender itself is based elsewhere.
Is PO Box 4501 a physical office I can visit?
No evidence indicates that PO Box 4501 is a public customer-service office. A PO Box is primarily a postal-routing address.

What should I do with mail addressed to someone who has moved?
You can return unopened mail marked “Return to sender – not known at this address.” Persistent correspondence may also be raised directly with the organisation named on the letter.
How can I check whether a letter is genuine?
