Published on June 15, 2026 • 7 min read • Written by SMS-OTPS Security Team
Whether you are switching carriers to save money, migrating to a premium temporary number system to protect your personal identity, or simply consolidating your mobile lines, you will need a Porting Authorisation Code (PAC).
Giffgaff, one of the UK’s most popular mobile virtual network operators (MVNOs) running on the O2 network, makes it relatively simple to request your transfer code. In this comprehensive walkthrough, we reveal the 3 easiest ways to get your Giffgaff PAC code instantly.
What is a PAC Code and Why Do You Need It?
A **PAC code** is a unique 9-character alphanumeric identifier (formatted as three letters and six numbers, e.g., ABC123456). It serves as an official authorization token that allows your new mobile operator to securely transfer your active phone number from your previous provider.
Under Ofcom regulations, UK mobile carriers are legally obligated to issue your PAC code free of charge and within a few minutes of request. Using a PAC code is the only way to retain your original mobile number when moving to another service.
The 3 Ways to Get a Giffgaff PAC Code
Method 1: Request via Text (The Fastest Way)
The absolute quickest way to receive your PAC code is by utilizing the nationwide text-to-switch service:
- Open your messaging app on the Giffgaff SIM card.
- Text the word "PAC" (case-insensitive) to 65075.
- You will receive a return SMS from Giffgaff within 60 seconds containing your 9-digit PAC code, expiry date, and details of any account termination fees (which is usually zero on Giffgaff pay-as-you-go).
Method 2: Get it Online (Via Giffgaff Dashboard)
If your phone does not have an active cellular signal or you are using a virtual SIM configuration, you can request it online:
- Log into your official account at giffgaff.com.
- Navigate to the "Profile and Settings" section.
- Select the "Leave Giffgaff" option.
- Confirm your request, and the portal will display your PAC code on-screen instantly.
Method 3: Request by Phone Call
If you prefer speaking to customer support, dial 43430 (free of charge from your Giffgaff line) and select option 1. Follow the automated interactive prompt to confirm your identity, and your PAC code will be read to you and sent via SMS.
Transferring to Temporary or Burner SIM Services
Many privacy-conscious users switch from standard Giffgaff profiles to temporary, secure numbers. If you need clean UK virtual or physical lines to register profiles on platforms like WhatsApp, Telegram, or Tinder without exposing your daily driver identity:
Using a premium **Non-VoIP SMS gateway** like SMS-OTPS provides physical contract line pools that guarantee incoming OTP delivery and bypass anti-spam networks automatically.
Conclusion
Acquiring your Giffgaff PAC code takes less than a minute. Text "PAC" to 65075, save the 9-digit code, and hand it to your new service provider. Remember that your PAC code remains valid for exactly 30 days, so start your transfer before the expiry date!
