How to get a PAC code from Vodafone, O2, 3 or EE?

If you are switching mobile networks but want to keep your existing phone number, you will need a PAC code from your current provider. This guide explains how to request one from each of the four major UK networks - Vodafone, O2, Three and EE - and how to use it to transfer your number.

How to get a PAC code from Vodafone

To obtain a PAC code from Vodafone, contact their customer service. The fastest method is the text-to-switch service: text ‘PAC’ to 65075 and you will receive your code within minutes. Alternatively, you can call 191 from your Vodafone phone, 03333 040 191 from any other phone or visit a Vodafone store in person.

How to get a PAC code from O2

To request a PAC code from O2, text ‘PAC’ to 65075 for the quickest option. You can also call 202 from an O2 phone, 0344 809 0202 from any other phone or visit an O2 store in person.

How to get a PAC code from Three

To request a PAC code from Three, text ‘PAC’ to 65075. You can also call 333 from a Three phone, 0333 338 1001 from any other phone or visit a Three store in person.

How to get a PAC code from EE

To request a PAC code from EE, text ‘PAC’ to 65075. You can also call 150 from an EE phone, 07953 966 250 from any other phone or visit an EE store in person.

How to change mobile networks and keep the same number

Once you have your PAC code, you provide it to your new network and they handle the rest of the number transfer for you.

The full process is:

1. Request a PAC code from your current mobile network using one of the methods above. You may need to provide ID.
2. Contact your new provider and tell them you want to switch while keeping your number. Note that your PAC code is valid for 30 days from issue.
3. Provide your PAC code to the new provider so they can transfer your number across.
4. Follow your new provider’s instructions to finish set-up. This usually involves activating the new SIM and adjusting your phone settings.

Once the switch is complete, your phone number remains unchanged on the new network.

How long does the switch take?

Requesting a PAC code via text-to-switch typically takes just a few minutes. The actual number transfer to your new network is normally completed within one working day of providing the PAC code. Switches over weekends or bank holidays may take slightly longer, so it is best to request a code on a weekday morning if you can.

What if I don’t want to keep the same number?

If you would prefer to switch network and start fresh with a new number, you instead need a STAC code (Service Termination Authorisation Code). Text ‘STAC’ to 75075 to terminate your contract and move to a new provider with a brand-new number.

Can I transfer a disconnected number?

No - once a number has been disconnected, it cannot be ported to a new provider. If you want to keep your existing number, you must request a PAC code while your current contract is still active.

What if I have multiple numbers associated with my account?

Text-to-switch is not available for accounts with multiple linked numbers (for example, family or business plans). In that case, you will need to request a PAC code over the phone or through your provider’s online account portal instead.

How to check a contract’s status before switching

Before requesting a PAC or STAC code, you can review your contract terms by texting ‘INFO’ to 85075. Your provider will reply with details including any remaining contract length and early termination fees. Early cancellation charges typically equal around 90% of the contract’s remaining value, so it is well worth checking your obligations before triggering a switch.

What is a PAC code?

A PAC code is a nine-digit code used to transfer a mobile phone number between UK network providers. PAC stands for Porting Authorisation Code. You give it to your new provider as authorisation to port your number across from your old one.

Why was text-to-switch introduced?

Before 2019, switching mobile networks meant phoning your provider - and many operators charged a notice period that overlapped with the new contract, forcing customers to pay for two services simultaneously. Ofcom introduced the text-to-switch system in July 2019 to make switching faster, cheaper and less hassle. Ofcom estimated the change would save UK consumers around £10 million per year.

Check coverage before you switch

Before you commit to a new network, it is worth checking how well it actually performs in the places you live, work and travel. Streetwave independently measures and maps UK mobile coverage and network quality by driving the road network with calibrated test devices - giving you an evidence-based picture of which operator will actually serve you best.
