The number to top up your Vodafone Pay as you go account is 2345, which you call free from the Vodafone mobile you want to top up. You can also text 2345 or use a voucher dial string. All three methods are free and work directly from your handset.

How do I top up by calling 2345?

Call 2345 free from your Vodafone Pay as you go phone and follow the automated prompts. The call costs nothing and the credit is added straight away once your payment is confirmed.

If you are activating a brand new SIM, Vodafone requires a minimum top-up of £5. As Vodafone's own support page states: "To activate your SIM card, you'll need to top up a minimum of £5 or buy a Big Value Bundle." New SIM activations also need to be completed while connected to Wi-Fi.

For first-time registration on a new Pay as you go SIM, an alternative free number is available: 18829. Call it from your Vodafone mobile to register and make that initial top-up if 2345 does not work at the point of activation.

How do I top up by text?

Send a text to 2345 with the following format:

TOPUP [amount] [last four digits of your payment card]

For example, if you want to add £10 and your card ends in 4321, text: TOPUP 10 4321 to 2345. The text is free to send. You will get a confirmation text once the top-up goes through.

How do I top up with a voucher?

If you have a TopUp voucher, dial the following string directly from your phone:

*#1345*[your voucher number]#

So if your voucher number is 123456789123, you would dial: *#1345*123456789123# and press call. The credit is applied immediately once the code is accepted.

Does top-up work on all Vodafone accounts?

No. Vodafone confirms that "Top-up isn't applicable for Pay as you go Plus and VOXI accounts." If you are on either of those plans, the 2345 method will not apply to you. Standard Pay as you go is the account type these top-up options are designed for.
