Is a text from 75075 safe?

Whoever the sender, judge a text by what it asks, not the number it shows. Genuine organisations never ask you to share passwords, PINs or one-time codes, "verify" card details through a text link, or move money to a "safe account". An unexpected text doing any of those is a scam regardless of the code it came from — sender IDs can be spoofed.

Don't tap links in unexpected texts — go to the organisation's website or app directly.
Don't reply to suspicious messages — even "STOP" confirms your number is live to a scammer.
Forward scam texts to 7726 (free, all UK networks) so your network can act on the sender.
