About the 01790 dialling code

01790 is the UK geographic dialling code for Spilsby, allocated by Ofcom under the National Telephone Numbering Plan. It is used by landlines — and increasingly VoIP lines — registered to the Spilsby area.

A full Spilsby number is normally written as 01790 XXXXXX. You can dial the local part on its own from within the same area, or the full number from anywhere in the UK.

Because of UK number portability and internet calling, a 01790 number no longer guarantees the caller is physically in Spilsby. Fraudsters also "spoof" local codes like 01790 so an unknown call looks like a nearby business or neighbour — so treat an unexpected call on what is actually said, not on the area code alone.

Is a call from 01790 safe?

Most 01790 calls are ordinary local calls from Spilsby homes and businesses. The main risk to be aware of is "neighbour spoofing", where a scammer fakes a local 01790 prefix so you are more likely to answer. Never share bank details, passwords or one-time security codes with an unexpected caller, even when the number looks local — hang up and call the organisation back on a number you have verified yourself.

To call a 01790 (Spilsby) number from outside the UK, drop the leading zero and dial +44 1790 followed by the local number.

How to block and report 01790 spam calls

Block 01790 on your phone

  • iPhone: open Phone → Recents, tap the (i) next to 01790, scroll down and tap Block this Caller.
  • Android: open the Phone app, press and hold 01790 in your recent calls, then tap Block / Report spam.
  • Network level: EE, O2, Vodafone and Three all offer free spam-call blocking in their app or online account settings.

Report 01790

  • Scam texts: forward the message to 7726 (free) — it spells "SPAM" on the keypad — to report it to your mobile network.
  • Scam or fraud calls: report to Action Fraud on 0300 123 2040 (England, Wales & NI) or Police Scotland on 101.
  • Nuisance / marketing calls: report to the ICO and register with the free Telephone Preference Service (TPS) to reduce unsolicited sales calls.

How to stop unwanted calls for good

Blocking 01790 numbers stops that one number, but determined nuisance callers simply switch numbers. These steps cut the volume across the board:

  • Silence unknown callers. iPhone: Settings → Apps → Phone → Silence Unknown Callers. Android: open Phone → Settings → Caller ID & spam and turn on filtering. Unknown numbers go straight to voicemail.
  • Turn on your network's free spam shield. EE, O2, Vodafone, Three, Sky and most providers offer free spam/scam-call screening in their app or account settings.
  • Register with the Telephone Preference Service (TPS). It's free and legally obliges UK companies to stop unsolicited sales calls within 28 days.
  • Use a dedicated call-blocker app if nuisance calls are persistent — these screen against live community spam databases and can auto-reject flagged callers before your phone even rings.
  • Never engage to "opt out". Pressing a key to be removed only confirms your number is live and usually means more calls.
