PO Box 1020, Dagenham, RM9 6BF is a mailing address associated with customer communications processed in Dagenham and commonly linked with Paragon Customer Communications. Paragon provides large-scale print, document and customer communication services for organisations that need to send letters and other correspondence to their customers.
Receiving a letter displaying this address does not necessarily mean Paragon is the company contacting you about its own products or services. A communications provider can produce or process correspondence on behalf of another organisation, meaning the company named inside the letter is usually more important than the PO Box shown on the envelope.
As of 2026, Paragon continues to list a Dagenham operation at Evolution House, 12 Choats Road, Dagenham, Essex, RM9 6BF.
Who Is Behind PO Box 1020 Dagenham RM9 6BF?
PO Box 1020 has been associated with Paragon Customer Communications and its Dagenham mailing operations. Paragon specialises in managing high-volume communications for businesses and organisations.
Rather than every client maintaining its own large printing and mailing infrastructure, a specialist provider can prepare documents, print letters, organise postage and support the distribution process.
Paragon Customer Communications Limited is also an active UK-registered company. Companies House lists company number 07262428, with its current registered office at Park House, 16/18 Finsbury Circus, London, EC2M 7EB.
It is important to distinguish the company’s registered office from its Dagenham operational location. They serve different purposes and having different addresses is normal for a business operating from multiple sites.
Is PO Box 1020 Connected to Paragon Customer Communications?
The address is commonly associated with Paragon’s customer communications activities in Dagenham. However, readers should be careful about assuming that every letter bearing PO Box 1020 has been written directly by Paragon.
Paragon provides customer communications services that include document composition, data management, hybrid mail, postage optimisation and multichannel communications.
In practice, this means an organisation may create the underlying message while Paragon handles parts of the production and distribution process.
The organisation whose name, branding and account details appear in the letter should therefore normally be treated as the primary sender when checking why the communication was issued.
Is PO Box 1020 the Same as the Paragon Dagenham Office?
They should not automatically be treated as exactly the same address.
Paragon currently lists its Dagenham location as:
| Detail | Current Information |
| Organisation | Paragon |
| Dagenham Location | Evolution House |
| Street Address | 12 Choats Road |
| Town | Dagenham, Essex |
| Postcode | RM9 6BF |
| Telephone | +44 (0) 208 984 5800 |
The physical operation and PO Box share the RM9 6BF postcode, which helps explain the connection people make between them. Paragon’s official contact information confirms the Evolution House location.
However, a PO Box is a postal handling address, while Evolution House is a physical business location. Consumers should use the contact or response details provided by the organisation responsible for their particular letter rather than assuming the two addresses can always be used interchangeably.
Why Do Companies Use Paragon to Send Customer Letters?
Large organisations can send thousands or even millions of customer communications. Producing these internally can require substantial printing equipment, data-processing systems, postage management and operational resources.
Using a specialist communications provider allows companies to manage large volumes of correspondence more efficiently while maintaining consistent document production.
Paragon states that its customer communications services include hybrid mail, document composition, data management and postage optimisation. It also supports communications across physical and digital channels.
This type of outsourcing can be particularly useful for organisations regularly sending statements, customer notices, policy communications, service information and promotional material.
Why Would You Receive Mail From PO Box 1020 Dagenham?
Receiving a letter displaying PO Box 1020 may mean an organisation with which you have an existing or previous relationship has outsourced some part of its mailing operation.
The reason will depend on the company identified inside the letter. Common possibilities include account information, payment correspondence, policy changes, contractual updates, service notifications and promotional communications.
For example, the letter could relate to an existing customer account even though the envelope itself shows a mailing address rather than the company’s head office.
This is why the contents of the communication are more useful for identifying its purpose than the PO Box alone.
How Can You Identify the Actual Company That Sent the Letter?
If you do not immediately recognise the correspondence, inspect the letter carefully before taking any action.
Look for:
- Company Name: Check which organisation is clearly named within the letter
- Official Branding: Look for consistent logos and company information
- Account Reference: Compare any reference number with previous genuine correspondence
- Company Details: Check the registered company name and address in the footer
- Reason for Contact: Determine whether the subject matches a service, policy or account you recognise
- Privacy Information: Legitimate organisations commonly explain how customer information is handled
- Payment Details: Verify payment instructions independently before transferring money
If you remain unsure, find the organisation’s official website yourself and contact it using a telephone number or customer-service channel obtained independently from the letter.
This prevents a convincing-looking letter from controlling how you verify its own authenticity.

What Types of Letters May Come From PO Box 1020?
The precise content can vary because communications providers can work on behalf of different organisations.
A letter may contain an account update, billing information, policy documentation, renewal information, changes to terms, service notices or direct marketing.
The presence of PO Box 1020 therefore does not tell you exactly why the letter was sent.
Always identify the organisation responsible for the message and read the document in full before deciding whether any response is required.
Is Mail From PO Box 1020 Dagenham RM9 6BF Legitimate?
The appearance of PO Box 1020 on an envelope is not, by itself, evidence that the communication is fraudulent.
At the same time, an apparently genuine mailing address should never be treated as proof that everything contained in a letter is authentic. Fraudsters can copy company names, addresses, logos and other details from legitimate organisations.
A genuine-looking address is therefore only one factor to consider.
Check whether the communication corresponds with an account or organisation you recognise. Be particularly cautious when an unexpected letter asks for immediate payment, banking credentials, passwords or other sensitive information.
What Should You Do If the Letter Looks Suspicious in 2026?
Do not act solely because a letter creates a sense of urgency.
Common warning signs include unusually short payment deadlines, threats designed to make you act immediately, requests for unexpected personal information, unfamiliar payment details or contact information that differs from the organisation’s normal channels.
If anything looks suspicious, independently contact the company supposedly responsible for the communication.
For suspected fraud, UK reporting arrangements changed at the end of 2025. Report Fraud replaced Action Fraud on 4 December 2025 as the new fraud and cybercrime reporting service, with the existing 0300 123 2040 telephone number retained.
This is an important 2026 update because older online guidance may still tell consumers to use Action Fraud.
What Should You Do If the Letter Demands Payment or Mentions Debt?
A demand for money deserves additional verification, especially when you do not recognise the organisation or amount involved.
Do not ignore a potentially genuine financial communication, but do not make a payment simply because the letter appears official.
First identify which organisation claims that money is owed. Then contact that organisation independently and ask it to confirm the account, amount, reference number and reason for the payment.
If debt collection is mentioned, establish who the original creditor is and whether the account belongs to you before providing information or paying anything.
Keeping a copy of the correspondence can also be helpful if the issue needs to be investigated or disputed later.
What If the Letter Is Addressed to Someone Who Does Not Live With You?
Letters sometimes continue arriving for former residents after they have moved.
If the named recipient does not live at your address, avoid assuming the correspondence relates to you simply because it was delivered to your property.
You can follow the postal provider’s return-mail procedure or any appropriate return instructions shown on the envelope. Do not provide your own personal information merely to prove that another person has moved.
Where repeated correspondence continues, contacting the organisation responsible for the letters through its verified customer-service channels may help it update its records.
Can You Reply or Send Documents to PO Box 1020 Dagenham?
Do not automatically assume that PO Box 1020 is intended to receive customer replies.
A mailing address shown on an envelope can be used for processing, distribution or return-mail handling rather than general customer correspondence.
Check the letter itself for instructions about responding. If a company asks you to return documents, submit information online or contact a particular department, follow the verified instructions provided by that organisation.
Where sensitive documents are involved, independently confirm the destination before posting originals or copies containing personal information.
Can You Stop Receiving Marketing Letters From This Address?
If the letter is genuine direct marketing addressed specifically to you, you can normally contact the organisation responsible and object to the use of your personal information for direct marketing.
The Information Commissioner’s Office states that individuals have an absolute right to object to their personal information being used for direct marketing, including targeted advertising sent through the post.
However, stopping marketing does not necessarily stop all correspondence.
Companies may still need to send non-marketing communications concerning an existing account, contract, payment, policy, regulatory requirement or essential customer-service matter.
For this reason, requests to stop marketing should normally be made to the organisation responsible for the communication rather than simply to the company that physically processed the letter.

How Can You Contact Paragon Customer Communications in 2026?
Paragon’s current official contact information lists its Dagenham operation at Evolution House, 12 Choats Road, Dagenham, Essex, RM9 6BF, with the telephone number +44 (0) 208 984 5800.
Its contact system also separates enquiries into categories such as general enquiries, existing orders, invoices, HR matters and new business enquiries.
If your question concerns an account, bill, insurance policy, telecom service or another product provided by a different organisation, contacting that organisation directly is usually more appropriate.
Paragon may have processed the communication without being responsible for the underlying account or decision described in the letter.
Conclusion
PO Box 1020 Dagenham RM9 6BF is associated with customer communications processed through Dagenham and is commonly linked with Paragon Customer Communications.
Receiving mail displaying the address does not automatically indicate a scam, nor does it necessarily mean Paragon itself is the organisation trying to contact you. In many cases, the most important information is the company identified inside the correspondence and the reason it gives for contacting you.
Before making payments, providing personal information or returning sensitive documents, independently verify the organisation involved. For suspicious communications in 2026, remember that Report Fraud has replaced Action Fraud as the UK’s newer fraud-reporting service.
