How do I top up using a giffgaff top-up voucher?
Topping up your giffgaff balance with a voucher is easy, just follow the guide.
Purchasing a top-up voucher
giffgaff vouchers can be bought in most shops providing epay, payzone or paypoint services. Don't know where to find one of these shops near you? check this article for more details. You can also find them in Post Offices and most supermarkets.
If you can't find a giffgaff voucher at your favourite shop, you can get an O2 voucher, they also work. If you buy a voucher for O2, make sure to follow the steps described in the next sections, and not those printed on the voucher itself.
Redeeming a top-up voucher
The voucher can be redeemed from your giffgaff mobile, or online.
From your mobile
Call 43430 for free with your giffgaff phone and follow the voice prompts along the way.

- Click on Redeem a voucher
- Enter your voucher's 16 digits code in the field - if the code is rejected, see here how to solve it.
- Click on "Redeem".
Please note that top-up vouchers can take up to 24 hours to be applied to your account balance.
Activating your SIM using a top-up voucher
You can also use a voucher to activate your new SIM, but you must redeem the first voucher online - the 43430 top-up number will not be available until your SIM is activated.

The top-up steps are similar to those described in the section above, just click on Redeem a Voucher in "By top-up voucher" (see image in spoiler below).
Once this first top-up has been done online, you'll be able to redeem your next vouchers with your mobile phone.
