0330 numbers are UK non-geographic phone numbers regulated by Ofcom. They cost the same to call as a standard 01 or 02 landline, and calls to them are included in most mobile and landline inclusive minutes bundles.
This guide covers what a 0330 number is, how much it costs to call from a mobile and landline, who uses them, how they compare to other 03 numbers such as 0333, and whether your business should get one.
What is a 0330 number?
A 0330 number is part of the UK 03 number range, which Ofcom introduced to give organisations a non-geographic phone presence without the higher charges associated with 084x or 087x service numbers.
Non-geographic means the number is not tied to a physical location or area. Callers cannot tell from the number where the organisation is based, which makes 03 numbers popular with charities, government bodies and businesses that operate nationally.
The 03 range includes several sub-ranges: 030, 0300, 0330, 0333, 0344, 0345 and others. Within the range, 0330 numbers are particularly common among NHS trusts, charities and large public-sector organisations, though any business can obtain one.
How much does it cost to call a 0330 number?
Calls to 0330 numbers cost the same as calls to any standard UK landline starting 01 or 02. The key point is that they are included in your inclusive minutes bundle on any UK mobile or landline tariff.
| Calling from | With inclusive minutes | Without inclusive minutes |
|---|---|---|
| UK mobile (any network) | Included in bundle | Standard per-minute rate (typically 3p to 15p/min) |
| BT landline | Included in plan | BT standard rate (varies by plan) |
| Virgin Media landline | Included in plan | Virgin standard rate |
| Sky landline | Included in plan | Sky standard rate |
| From abroad | International rates apply | International rates apply |
Under Ofcom's rules, the cost to call any 03 number must be the same as calling an 01 or 02 number from the same plan. This is set in legislation and applies to all UK providers. If a provider charges more for 03 numbers than for 01/02 calls, they are in breach of the rules.
0330 vs other UK number types
| Number range | Type | Cost to caller | Typical use |
|---|---|---|---|
| 01 / 02 | Geographic | Standard rate | Local businesses, home offices |
| 03 (incl. 0330, 0333) | Non-geographic | Standard rate | National businesses, charities, public sector |
| 0800 / 0808 | Freephone | Free from mobile and landline | Customer service lines, marketing |
| 0844 / 0845 | Non-geographic | Higher rate (service charge) | Falling out of use; often avoided by callers |
| 0871 / 0872 / 0873 | Non-geographic | Premium rate (up to 13p/min) | Competition lines, premium services |
| 09xx | Premium rate | Very high rate | Adult services, competition lines |
What is the difference between 0330 and 0333?
Both 0330 and 0333 are in the 03 non-geographic range regulated by Ofcom. From the caller's perspective, they are identical in terms of cost: both are charged at the standard 01/02 rate and both count against inclusive minutes.
The difference is in which organisations tend to use each range:
- 0330 numbers are heavily used by NHS trusts, charities, local government, and large national organisations such as HMRC and the Driver and Vehicle Licensing Agency (DVLA).
- 0333 numbers are widely used across the business sector and are very common among insurance companies, utility providers, and businesses of all sizes.
For a business choosing a non-geographic number, either range works equally well. The choice often comes down to which number is available from your telecoms provider.
Who uses 0330 numbers?
0330 numbers are most commonly used by:
- NHS trusts and clinical commissioning groups
- Charities and housing associations
- Local councils and government agencies
- Insurance companies and financial services firms
- National retailers with customer service lines
- Utility companies (energy, water, broadband)
Are 0330 calls genuine?
0330 numbers themselves are not inherently associated with scams. The number range is regulated by Ofcom and used legitimately by many well-known organisations. However, fraudsters do use 0330 numbers just as they use 01 and 02 numbers.
If you receive an unexpected call from a 0330 number claiming to be from HMRC, a bank or another authority, the best approach is to hang up and call the organisation back using the number on their official website. Legitimate organisations do not ask for payment or personal details unexpectedly over the phone.
Should your business get a 0330 number?
A 0330 number makes sense if your business operates nationally and you do not want your geographic location implied by your phone number. It signals a professional, established presence without the higher charges callers associate with 084x or 087x numbers.
For most small businesses and sole traders, a local 01/02 number or a mobile number is perfectly adequate. Callers in your area often prefer a local number as it signals you are nearby.
