A PO Box provides an alternative postal address for receiving mail without displaying a home or workplace address. In the UK, individuals and businesses can apply for one through Royal Mail and choose either to collect their post from a Customer Service Point or have it delivered to their registered address.
What Is a PO Box in the UK?
A Post Office Box, commonly called a PO Box, is a numbered postal address managed by Royal Mail. Instead of sending letters to a residential or business building, the sender addresses them to a specific PO Box number and postcode.
A typical address may appear in this format:
Recipient or business name
PO Box 1234
Town or city
Postcode
Royal Mail still requires the applicant’s real address when setting up the service. Therefore, a PO Box improves public-facing privacy but does not make the recipient anonymous to Royal Mail.
Who Can Get a PO Box?
Royal Mail offers PO Boxes to both personal and business customers. The service may be useful for:
- People who do not want to publish their home address
- Home-based business owners
- Freelancers and sole traders
- Charities and community organisations
- Businesses receiving customer correspondence
- People who regularly move between properties
- Organisations running postal campaigns or competitions
Applicants need a valid UK address connected to the delivery office serving the requested PO Box. The payment card used for an online application must also be registered to the address entered on the application.
What Types of PO Box Are Available?
Royal Mail provides two main options: PO Box Collect and PO Box Deliver. Both supply a dedicated PO Box address, but the way the mail reaches the recipient is different.
| Service | How It Works | Suitable For |
| PO Box Collect | Royal Mail keeps the mail at a designated Customer Service Point for collection | People who want greater separation from their home address |
| PO Box Deliver | Royal Mail delivers PO Box mail to the address stated on the application | People who want privacy without travelling to collect their post |
PO Box Collect is generally cheaper when purchased for six or twelve months. However, applicants should check the location and opening hours of the relevant Customer Service Point before choosing it.
How Much Does a PO Box Cost in the UK?
As of September 2026, the published prices include VAT and vary according to the service and payment period.
| Duration | PO Box Collect | PO Box Deliver |
| Monthly by Direct Debit | £50.40 | £50.40 |
| Six months | £243.00 | £276.60 |
| Twelve months | £416.40 | £499.80 |
Monthly subscriptions have a minimum term of three months and are available through Direct Debit. Prices can change, so applicants should confirm the amount shown during the application process. Royal Mail’s current PO Box prices provide the latest figures.
For business pricing, Royal Mail may display amounts excluding VAT. For example, a monthly price of £42 excluding VAT becomes £50.40 when standard-rate VAT is added.
How Can Someone Apply for a PO Box Online?
Applying online is normally the quickest option. Royal Mail says an online application can take up to seven working days to set up.
The process involves the following steps:
- Visit Royal Mail’s PO Box application service.
- Enter the applicant’s postcode and address.
- Choose between PO Box Collect and PO Box Deliver.
- Select a monthly, six-month or twelve-month term.
- Provide the required personal or business details.
- Pay using a debit or credit card registered to the application address.
- Wait for Royal Mail to approve and activate the service.
- Use the new PO Box address only after receiving confirmation.
Applicants should check every detail before submitting the form. A mismatch between the billing address and application address could delay or prevent the application from being completed.
How Can Someone Apply by Post?
People who cannot or do not want to apply online can download and complete Royal Mail’s PO Box application form.
The completed form should be sent with the required proof of identity and payment to:
Royal Mail PO Box Team
Dearne House
Cortonwood Drive
Brampton
Barnsley
S73 0UF
The postal application form explains which identity documents are acceptable. Sending original documents should be avoided unless the form specifically requires them.
Postal applications take at least ten working days to process and may take longer if information or evidence is missing. Royal Mail therefore recommends applying online where possible.
What Documents Are Needed for a PO Box?
The exact requirements may depend on whether the applicant is applying as an individual, organisation or business. A postal application normally requires proof of identity, while an online application uses address and payment-card checks.
Applicants should be ready to provide:
- Their full legal name
- Their current UK address
- Contact information
- Business or organisation details, where applicable
- An eligible payment method
- Proof of identity if applying by post
- A completed Direct Debit mandate for relevant payment arrangements
All names that will receive mail may need to be declared. Applicants should read the current form and terms rather than assuming that one subscription automatically covers unrelated people or trading names.
How Long Does It Take to Set Up a PO Box?
An online PO Box application can take up to seven working days. A postal application takes at least ten working days because Royal Mail must receive and manually process the documents.
Delays may occur if:
- The payment card is registered to a different address
- Proof of identity is missing or unclear
- The application contains inconsistent information
- The selected service is unavailable at the local delivery office
- Royal Mail needs additional information
Mail should not be addressed to the new PO Box until Royal Mail confirms that the service is active.
How Is Mail Collected From a PO Box?
With PO Box Collect, Royal Mail holds the mail at the Customer Service Point connected to the box. The customer can collect it during that location’s published opening hours.
The account holder should confirm what identification or collection authority is required, particularly if another person will collect the post. Businesses may also need a reliable internal procedure for recording collections and passing important letters to the correct employee.
A PO Box is not necessarily a physical box that the customer unlocks. In many cases, Royal Mail staff retrieve and hand over the held mail at the collection point.
Can PO Box Mail Be Delivered to a Home Address?
Yes. PO Box Deliver allows mail sent to the PO Box to be delivered to the physical address stated in the application.
This option allows a person or business to publish the PO Box rather than the underlying address while continuing to receive mail at home. It is convenient for home-based businesses, although it costs more than the longer PO Box Collect plans.
Only customers who have selected PO Box Deliver should expect PO Box mail to arrive at their application address.
Can a PO Box Receive Parcels?
A PO Box should primarily be treated as a service for receiving eligible Royal Mail mail. Whether a particular parcel can be accepted may depend on its size, delivery service and carrier.
Some private couriers will not deliver to PO Box addresses because they require a physical address or a signature at a particular building. Retailers may also refuse PO Box addresses during checkout.
Anyone expecting valuable, oversized or courier-delivered parcels should confirm acceptance with both the sender and carrier. A parcel locker, virtual office or physical business address may be more suitable where regular parcel deliveries are required.
Can a Business Use a PO Box?
A business can use a Royal Mail PO Box as a customer correspondence or general mailing address. This may help a home-based company present a consistent postal address while keeping its residential location away from advertisements and marketing materials.
However, a Royal Mail PO Box cannot be used as a limited company’s registered office address. Companies House requires an “appropriate” physical address where company post can be received and acknowledged.
A company that does not want to publish a director’s home address can consider an accountant, solicitor or registered office service that meets the official conditions. Companies House confirms that Royal Mail PO Boxes are not accepted.
A business should also check the address requirements of banks, insurers, payment providers, HMRC and licensing bodies. A PO Box may be accepted as a correspondence address without being accepted as the organisation’s official or verified address.
What Are the Advantages of Having a PO Box?
A PO Box can offer several practical benefits:
- It keeps a home address away from general customers and readers.
- It provides a consistent address when a person moves locally.
- It separates personal post from business correspondence.
- It can create a more organised way to manage incoming letters.
- PO Box Collect prevents business mail from being delivered to the home.
- It may reduce the risk of important letters being mixed with household post.
The service is particularly useful when an organisation needs a reliable correspondence address but does not operate from a public office.
What Are the Disadvantages of a PO Box?
A PO Box does not replace every type of business or residential address. Its main limitations include:
- Annual fees can be significant.
- Some retailers and couriers will not send parcels to it.
- A collection service requires travel to a Customer Service Point.
- Collection hours may be limited.
- It cannot be used as a limited company’s registered office.
- Financial institutions may still request a residential address.
- It does not provide a workspace or meeting location.
- Mail may be interrupted if the service expires without renewal.
Applicants should compare these restrictions with the expected volume and type of post before paying for a long-term subscription.
Is a PO Box the Same as a Virtual Office?
A PO Box and a virtual office are different services.
A PO Box provides a numbered Royal Mail address for receiving eligible post. A virtual office usually supplies a conventional street address and may include scanning, forwarding, telephone answering or meeting-room access.
Some virtual office providers offer an address that can be used as a company’s registered office, but the address must satisfy Companies House requirements. A basic mailbox or PO Box-style service may not qualify.
A PO Box is often suitable for straightforward correspondence. A virtual office may be better for a limited company needing a compliant registered office and broader administrative support.
How Can a PO Box Address Be Used Correctly?
Once the service is active, the recipient should provide the complete address exactly as confirmed by Royal Mail. The recipient’s name or approved business name should be placed above the PO Box number, followed by the town and postcode.
The address can be added to:
- Website contact pages
- Customer service correspondence
- Invoices and order documentation
- Business cards
- Advertising materials
- Membership forms
- Postal return instructions
Businesses must still display any legally required address information. Publishing a PO Box does not remove statutory disclosure obligations.
What Happens When a PO Box Is Cancelled?
When a PO Box is cancelled or expires, Royal Mail will no longer be required to hold or deliver mail under that service. The customer should update senders before the closing date and replace the address across websites, stationery and business records.
If an organisation expects mail after closure, it should check whether a temporary redirection is available. Royal Mail indicates that mail can be redirected from an active PO Box for a maximum of six months, subject to the relevant conditions.
Is Getting a PO Box Worth It?
A PO Box can be worthwhile for people and small businesses that receive regular letters and want to avoid publishing a home address. PO Box Deliver offers convenience, while PO Box Collect creates a clearer separation between the public postal address and the home.
It may be less suitable for someone who mainly receives courier parcels or needs a legally compliant registered office. Before applying, the customer should compare the annual cost with alternatives such as a virtual office, business mailbox or professional adviser’s address.
