Frequently asked questions

How much do 0333 numbers cost to call?

Calls to 0333 (and other 03) numbers are charged at the same rate as calls to standard 01 and 02 landline numbers, and are included in any inclusive-minute bundle the caller has.

What’s the difference between 0333 and 0800?

0333 numbers are charged to the caller at normal landline rates (and included in bundles), while 0800 numbers are completely free for the caller and cost the business more per minute.

Can I forward an 0333 number to my mobile?

Yes — like all LineHQ numbers, an 0333 line forwards to any phone you choose, with full call handling in the dashboard.

Are 0333 numbers included in customers’ inclusive minutes?

Yes. Calls to 0333 numbers are treated exactly like calls to 01 and 02 landlines, so they count towards the inclusive call allowances on most UK mobile and landline plans. For many customers that means ringing your 0333 number costs nothing extra — a clear advantage over premium-rate or 084/087 numbers.

Can I port my existing 0333 or 03 number?

Yes. Existing 03 numbers, including 0333 and 0345 lines, can usually be ported to LineHQ for free so you keep the number your customers know. It keeps working throughout the transfer and switches to LineHQ’s forwarding on completion, typically within a couple of weeks.

Is an 0333 number better than an 0845 number for my business?

For most businesses, yes. Calls to 0333 numbers cost the caller the same as a normal landline call and are included in their bundle, whereas 084 numbers add a service charge on top. An 0333 line therefore looks fairer and more modern, while still giving you a single national presence.

Does an 0333 number tie me to a location?

No. An 0333 number is national and carries no geographic dialling code, so it doesn’t tie you to any city or suggest where you’re based. It’s a good fit for support and sales lines that serve the whole UK, and it forwards to your mobile, office or team just like any LineHQ number.

Can I port an existing 0333 number to LineHQ?

Yes. Most 0333 business numbers can be ported to LineHQ, subject to the current provider and account details matching. Do not cancel the old service before the port completes.

When should I choose 0333 instead of 0800?

Choose 0333 when you want one national number that callers pay for at standard 01/02 rates. Choose 0800 when removing caller cost is worth the higher inbound cost to the business.
