If you are new to the UK, using the Post Office may seem confusing at first — especially if you are used to a different system in your home country. Whether you want to send a birthday card, post a document, or ship a parcel abroad, this guide will show you how everything works step by step.


What Is the Post Office?

The Post Office is a nationwide service provider that handles mail, banking, and other everyday services. It is not the same as Royal Mail, which physically delivers letters and parcels.

Here’s how it works:

  • The Post Office is the place where you go to send and collect mail, buy stamps, and access services.
  • Royal Mail is the delivery company that transports your letters and parcels.

You can find Post Offices in most towns and even inside convenience stores or newsagents.

Common Things You Can Do at a Post Office

  • Buy stamps
  • Send letters and parcels in the UK or internationally
  • Track your deliveries
  • Collect or return online shopping orders
  • Pay bills or top up pre-paid cards
  • Apply for passport and driving licence services
  • Use basic banking services with most UK banks

Sending a Letter or Card

To send a standard letter in the UK:

  1. Write the full UK address clearly on the front
  2. Buy a stamp (First Class or Second Class)
  3. Stick the stamp on the top right corner
  4. Drop the letter in a red Royal Mail postbox or hand it to the Post Office counter

Stamp options:

  • First Class: Arrives in 1–2 working days

You can buy a single stamp or a booklet of multiple stamps.

Tracking and Proof of Delivery

Most tracked services offer:

  • Online tracking
  • Email or text notifications
  • Signature on delivery (optional)

Always keep your receipt — it includes the tracking number and reference in case the item is lost or delayed.


Receiving Parcels in the UK

When someone sends you a parcel:

  • It will usually arrive at your home address
  • You may get a text or card if you are not home
  • Some deliveries go to a local Post Office or parcel locker for collection

Bring ID (such as a driving licence or utility bill) to collect a held parcel.


Returning Online Orders

Many UK online shops (like Amazon, ASOS, or eBay sellers) allow easy returns via the Post Office. You may be given:

  • A QR code to show on your phone
  • A pre-printed label to attach to your package

Just bring the item and label to the Post Office — they will scan and send it for you.

Sending Mail Abroad

To post internationally:

  1. Ask for international delivery at the counter
  2. Complete a customs declaration form if needed
  3. Choose from economy or tracked options

Some restricted items (like food, cosmetics, or batteries) cannot be sent overseas. Ask the clerk or check the Royal Mail website if unsure.


Opening Hours and Queues

Most Post Offices are open:

  • Monday to Friday, 9:00am to 5:30pm
  • Saturday, 9:00am to 12:30pm or 1:00pm

Some branches inside supermarkets may stay open longer.

Lines can be long during lunch or after work hours — try to visit in the morning if possible.


Final Tips for Newcomers

  • Always include a return address on your package
  • Use block letters for easier reading
  • For valuable items, consider Signed For or Special Delivery
  • If you send a lot of mail, ask about Click & Drop (online postage)
