Choose the outcome first
For most single-number UK switches, a PAC is the route for retaining the existing number. STAC is the switching route when you do not want to retain it. These are not discount codes and are not interchangeable.
Request the correct code
Ofcom describes texting PAC to 65075 or STAC to 75075 from the relevant line. Multi-number accounts can require the provider’s online or telephone process. A code normally remains valid for 30 days; check the accompanying information before proceeding.
Read the leaving information
Requesting a code does not erase a remaining commitment. Look for early-exit information, credit and device obligations. Keep the answer in writing where possible and distinguish a service charge from a separate handset repayment.
Let the receiving provider organise it
Supply the valid code to the new provider using its official process. Ofcom describes completion within one working day once the receiving provider has the required code and information. Do not separately cancel a number you intend to retain without understanding the consequences.
Check both sides afterwards
Test incoming and outgoing calls, messages and data, then check the final statement and any separate payments. If the transfer is delayed, raise the issue with the receiving provider. Keep dates and correspondence; independent guidance cannot submit or repair a port request.
Make a small, useful record.
Keep the provider name, agreement type, relevant date and a brief description of the question. Leave out passwords, full payment details and activation codes. The aim is to prepare a precise conversation, not to collect unnecessary private information.
Limeayhaven can explain general information. Account authentication, current eligibility, line changes and formal requests belong with the official provider.
