How to Get a PAC Code from Any UK Network [2026 Guide]
Switching mobile networks in the UK has never been easier thanks to PAC codes. Whether you're moving to a better deal or upgrading your business mobile service, understanding how to get a PAC code is essential for keeping your existing phone number whilst changing providers.
This comprehensive guide explains everything you need to know about obtaining a PAC code from any UK network, including step-by-step instructions for EE, O2, Vodafone, and Three, plus timelines and what happens after you've made your request.
What Is a PAC Code and Why Do You Need One?
A PAC (Porting Authorisation Code) is a unique nine-character code that allows you to switch mobile networks whilst keeping your existing phone number. Without a PAC code, you'd need to get a new number when changing providers—which can be particularly disruptive for businesses where your mobile number is tied to your professional identity.
Since 2019, Ofcom regulations have made it significantly easier to request a PAC code. Networks must provide your code immediately via text message, and the switching process has been streamlined to complete within one working day in most cases.
How to Get a PAC Code: The Text-to-Switch Method
The fastest and easiest way to get a PAC code from any UK network is through the text-to-switch service. This universal method works across all major providers and delivers your code within 60 seconds.

- Receive your code: You'll receive a text reply within 60 seconds containing your nine-character PAC code
- Note the expiry date: Your PAC code is valid for 30 days from the date of issue
- Check your account details: The text will also include your account balance and any outstanding contract information
This standardised service is free to use and works 24/7, making it the recommended method for most users who want to obtain a PAC code quickly.

Alternative Methods: How Do I Get a PAC Code Without Texting?
Whilst texting is the quickest method, some users may need alternative ways to request a PAC code:
Live Chat Services
Most UK networks now offer live chat through their websites or mobile apps. Simply ask the adviser for your PAC code, verify your identity, and they'll send it to your mobile via text.
Retail Stores
You can visit a physical store for your network provider. Bring photo ID and your mobile phone. Staff can generate your PAC code on the spot, though this method typically takes longer than digital options.
Written Requests
You can write to your provider's customer services address, though this is the slowest method and rarely used. Your network must respond within two working days.
PAC Code Request Timeline: What to Expect
Understanding the timeline for your PAC code request helps you plan your switch effectively:
| Stage | Timeframe | Details |
|---|---|---|
| PAC code delivery | Within 60 seconds | Instant via text message using 65075 |
| PAC code validity | 30 days | Must use code within 30 days or request a new one |
| Switching completion | 1 working day | From when you provide PAC to new network |
| Number transfer | Usually within hours | Often completes same working day |
| Old account closure | Same day as switch | Automatic when number transfers |
What Information Comes with Your PAC Code?
When you request a PAC code, the text message includes more than just the nine-character code. You'll receive:
- Your unique PAC code: Nine characters (letters and numbers)
- Expiry date: Valid for 30 days from issue
- Account balance: Any credit remaining or outstanding charges
- Contract status: Whether you're in or out of contract
- Early termination fees: If applicable, the amount you'll owe
- Customer service details: How to contact your network with questions
This transparency ensures you know exactly what to expect financially when you switch networks.
Using Your PAC Code: Step-by-Step Process
Once you've obtained your PAC code, here's how to use it to complete your switch:
1. Choose Your New Network
Select your new provider and the contract or SIM-only deal that suits your needs. Many businesses benefit from Connection Technologies' tailored mobile solutions that offer better rates and dedicated support for multiple lines.
2. Provide Your PAC Code
When signing up with your new network, you'll be asked if you want to keep your existing number. Provide your PAC code when prompted. You can do this:
- During the online checkout process
- By calling your new network's customer services
- In-store when collecting your new SIM
- After receiving your new SIM via your online account
3. Choose Your Switch Date
You can either:
- Switch immediately (usually within one working day)
- Schedule a specific date within the 30-day validity period
For businesses, scheduling allows you to plan the transition around operational needs.
4. Insert Your New SIM
On the switching day, your old SIM will stop working. Insert your new SIM card, and within hours (often sooner), your number will be active on your new network.
5. Test Your Service
Make a test call and send a text message to confirm everything is working correctly. Your contacts don't need to do anything—your number simply moves to the new network.
What Happens to Your Old Contract After Using a PAC Code?
Using a PAC code automatically triggers the cancellation of your old mobile contract. Here's what you need to know:
If You're Out of Contract
Your account will close automatically on the switch date with no penalties. Any remaining credit will typically be refunded, and outstanding charges will be billed on your final statement.
If You're Still in Contract
You'll be charged early termination fees, which usually equal the remaining monthly payments on your contract. These appear on your final bill from your old network. The PAC code information text will specify exactly how much you'll owe.
Direct Debits and Final Bills
Don't cancel your direct debit until you've received and paid your final bill, which typically arrives within 4-6 weeks. This bill includes any early termination fees, final month's charges, and adjustments for partial months.
PAC Code vs STAC Code: What's the Difference?
It's important to understand the distinction between these two codes:
- PAC (Porting Authorisation Code): Use this when switching networks and keeping your existing phone number
- STAC (Service Termination Authorisation Code): Use this when cancelling your contract and NOT keeping your number
Most people and businesses want to keep their established phone numbers, making the PAC code the right choice. To get a STAC code, text 'STAC' to 75075 instead.
Common Issues When Requesting a PAC Code
Didn't Receive Your Code?
If you don't receive your PAC code within 60 seconds:
- Check you sent 'PAC' to 65075 (not 75075, which is for STAC codes)
- Ensure you have signal and can receive text messages
- Try again or contact your network directly
- Check with your network if there are any account restrictions
PAC Code Has Expired
If your 30-day validity period has passed, simply request a new PAC code using the same methods. There's no limit to how many times you can request one.
Account in Someone Else's Name
If your mobile contract is in a different name (such as a business account or family member's name), the account holder must request the PAC code. For business accounts with multiple lines, speak to your account manager or Connection Technologies can assist with bulk transfers.
Business Considerations: Switching Multiple Lines
For businesses with multiple mobile lines, switching networks requires additional planning:
Staggered vs Simultaneous Switching
Consider whether to:
- Switch all lines simultaneously: Ensures consistency but requires careful coordination
- Staggered approach: Test service quality with a few lines before committing all numbers

- Managing early termination fees and budgeting
- Setting up new accounts with better business rates
- Ensuring continuity of service for critical business functions
Costs and Fees Associated with PAC Codes
Understanding the financial implications of switching is crucial:
PAC Code Request: Free
Requesting a PAC code is always free, regardless of your network or method. Networks cannot charge you for providing this code.
Early Termination Fees
If you're leaving before your contract ends, you'll typically pay the remaining monthly fees in one lump sum. For example, with six months remaining on a £30/month contract, expect to pay around £180.
Outstanding Handset Costs
If your contract included a phone, you might have separate device payment plans. These may need to be settled or could continue independently of your mobile service.
Final Month Pro-Rata Charges
You'll be charged for the days you used service in your final month, calculated on a pro-rata basis.
Tips for a Smooth Network Switch
Follow these best practices when using your PAC code:
- Check your contract end date: Switching just before renewal avoids early termination fees
- Compare total costs: Factor in termination fees when evaluating new deals
- Backup important data: Save contacts and messages before switching
- Note your voicemail: Set up voicemail on your new network and save any important messages from your old one
- Update two-factor authentication: Ensure you can still access accounts that text verification codes during the switch period
- Inform key contacts: Though your number stays the same, let important contacts know you're switching in case of brief disruption
- Time it strategically: Switch on a weekday when both networks' support teams are fully available
- Keep your old SIM temporarily: Don't dispose of it immediately in case you need to access any information

Frequently Asked Questions About PAC Codes
Can I cancel a PAC code request?
Yes. Simply don't provide the PAC code to a new network, and it will expire after 30 days. Your service with your current network continues unaffected. There's no automatic cancellation process—just let the code expire if you change your mind.
How long does a PAC code last?
Every PAC code is valid for exactly 30 days from the date of issue. After this period, you'll need to request a new code if you still want to switch networks.
Can I get a PAC code if I owe money?
Yes, networks must provide your PAC code even if you have outstanding charges. However, you'll still need to pay any owed amounts. Your old network will send a final bill including all outstanding fees, which you're legally obligated to pay.
Will I lose my phone number if I don't use the PAC code?
No. If you don't use your PAC code within 30 days, it simply expires and your service continues as normal with your current network. Your number remains yours until you actively switch or cancel your account.
Can I switch networks if I'm on a business account?
Yes, but the account holder (usually the business owner or designated administrator) must request the PAC code. Individual employees typically cannot request PAC codes for business-owned numbers. Connection Technologies can manage this process for businesses with multiple lines.
