Calls from 01403 543 XXX sometimes link to 'parcel undelivered' or 'card details expired' courier scams. The caller asks you to confirm a delivery address or re-enter card details on a follow-up SMS link. Real UK couriers (Royal Mail, DPD, Evri) handle these via the apps you signed up to, not by phone.
If a 01403 543 XXX number called you and you're not sure who it was, the safest steps are: don't return the call until you've verified it (search the full number online first), don't share personal or financial details, and register the number with the Telephone Preference Service (TPS) if it's a marketing call. Persistent unwanted calls can be reported to Ofcom and the ICO. To block a specific number on most UK mobiles and landlines, you can also enable network-level call screening through your provider.
