Is 444 safe, and is it spoofed?

A short code cannot be spoofed in the way an ordinary phone number can, because you are the one starting the conversation. The risk runs the other way: fraudsters send texts that claim to be from a service like this one and ask you to reply or tap a link.

If a text or call is trying to rush you, threaten you, or get a password, one-time code or payment out of you, it is a scam whatever number it shows. Read our guide to the UK number ranges scammers use and how to spot a smishing text, and forward anything suspicious free to 7726.

Where this came from

We do not guess short codes. Every entry in this directory was checked against the organisation that runs the code, or against gov.uk or the regulator:

Checked against these sources on 13 August 2026. Short codes and their charges do change — if the operator’s page now says something different, believe the operator.

Checking an ordinary number instead

Short codes are not in Ofcom’s numbering data — only full UK numbers are. If it is a normal 01, 02, 03, 07, 08 or 09 number you want to identify, put it into the phone number checker and you will get its type, its area and the provider Ofcom allocated the range to.

Is 444 free?

Free. Listed as free in Three's Pay As You Go price guide.

Who runs 444?

Three UK. 444 is Three's free automated line for topping up and checking your pay as you go balance. We verified this against the operator's own published information on 13 August 2026; the sources are linked on this page.

Is 444 a scam number?

No. A short code cannot be spoofed in the way an ordinary phone number can, because you are the one starting the conversation. The risk runs the other way: fraudsters send texts that claim to be from a service like this one and ask you to reply or tap a link.

I got a text from a short code I do not recognise – what should I do?

Do not tap any link in it and do not reply unless you are certain who the sender is. If it is marketing from a company you know, replying STOP to the short code shown in the message opts you out free. If it is unsolicited, forward it to 7726 free of charge and delete it - replying to an unknown sender only confirms your number is live.
