How much does it cost to call a 01621 number?

Calls to 01621 numbers are standard geographic landline calls, charged at your provider’s normal UK landline rate and usually included in inclusive minutes — the same as calling an 03 number.

I had a missed call from a 01621 number — is it a scam?

Not necessarily, but be careful: scammers spoof local codes such as 01621 so a call looks like it’s from Maldon and you’re more likely to answer. If in doubt, hang up and call the organisation back on a number you find independently.

How do I dial a Maldon number from abroad?

Drop the leading 0 and add +44. A number written as 01621 XXXXXX becomes +44 1621 XXXXXX when dialled internationally.

Can this tool tell me who owns the number?

No. It shows the area of the dialling code and the provider Ofcom allocated the number range to — not the individual or business holding a specific number, which may also have been ported to another network.

Where is the 01621 area code?

The 01621 dialling code is the UK geographic area code for Maldon. Because 01621 is a geographic (01/02) code, a number using it is tied to the Maldon dialling-code area — though with modern hosted telephony (VoIP) a business can keep a 01621 number after moving premises, so the code reflects the number’s designated area rather than a guaranteed physical location today.

Ofcom currently lists 370 number blocks under 01621, of which 131 are allocated to 93 communications providers.

Maldon phone number format

A Maldon number is made up of a 5-digit area code followed by a 5 or 6-digit local number. Written in full it looks like 01621 XXXXXX (the Xs stand for the local digits). Ofcom has not reserved a fictitious drama range for 01621; for on-screen examples it recommends the unused 01632 960000–01632 960999 range.

Who holds 01621 number ranges?

Ofcom allocates 01621 numbers to providers in blocks. These providers hold the largest allocations under 01621:

Range holder (allocated by Ofcom)	Number blocks	Example range
BT	14	`01621 493XXX`
GCI Network Solutions Limited	11	`01621 210XXX`
Vodafone Ltd (C&W)	8	`01621 700XXX`
TalkTalk Communications Limited	4	`01621 492XXX`
DRD Communications Limited	2	`01621 750XXX`
Datazero Ltd	2	`01621 469XXX`
Digital Space Group Limited	2	`01621 207XXX`
Fuse 2 Communications Ltd	2	`01621 477XXX`

…and 85 more providers hold smaller allocations in this range.

Ofcom’s data shows the provider each number range was originally allocated to — not who holds an individual number today. Numbers are frequently moved (ported) between providers, and no public database reveals the person or business behind a specific number, so treat any service that claims to with suspicion.

Spotting spoofed 01621 scam calls

Fraudsters frequently spoof local dialling codes, faking the caller ID so a scam call appears to come from a Maldon (01621) number you might trust. Remember:

A familiar 01621 area code is not proof the caller is local or genuine — caller ID can be faked.
Banks, HMRC and the police will never ask you to move money or share passwords or one-time codes over the phone.
If a call feels off, hang up, wait a moment, and call the organisation back on a number from their official website or your statement.
Report nuisance calls to the ICO and forward scam texts to 7726 (free).
