UK number types

London 020 local

A geographic London number formatted as 020 X XXXX XXXX. Callers see a London identity and pay the same as a domestic landline call. Suitable for businesses with a London-facing brand, support lines, or marketing campaigns targeting Greater London.

Available codes include 020 3, 020 7, 020 8.

Regional local

A geographic number tied to a specific city or region. Used to signal local presence outside London or to run regional campaigns.

didlogic provides geographic UK numbers in Manchester (0161), Birmingham (0121), Liverpool (0151), Bristol (0117), Edinburgh (0131), Glasgow (0141), Leeds (0113), Sheffield (0114), Belfast (028), and 12 more UK cities.

UK national 03

A non-geographic number that callers pay at the same rate as a 01 or 02 geographic call, including from mobiles and within bundled minutes. Ofcom requires UK providers to treat 03 calls as inclusive within consumer minute packages. Useful when a single national presence matters more than a city identity.

UK 0800 / 0808 freephone

A toll-free number. The caller pays nothing, the receiver pays per minute. Free for callers from both UK landlines and mobiles since 2015. Used for inbound sales, customer support, and high-trust campaigns.

UK mobile 07

A mobile-format UK number starting 07. didlogic provides UK mobile numbers with inbound voice and full inbound and outbound SMS. Useful when the number must look like a person rather than an office, including for SMS verification flows and AI voice agents.

What teams build with UK numbers on didlogic

UK contact centre setup

A new UK-facing contact centre needs local CLI, London 020 and regional numbers, an inbound SIP trunk, and outbound routes that pass UK STIR/SHAKEN equivalent attestation. didlogic provisions the numbers and the SIP trunk on the same AS13006 connection, with the native UK CLI presented on outbound calls.

What to expect when buying a UK number

Activation time

Most UK numbers activate within 8 hours of order. Orders that need local address verification can take up to 48 hours.

Address verification

UK geographic numbers (020, 0161, 0121, and other local codes) may require a UK-registered service address depending on the specific range and Ofcom rules for that operator. 0800, 03, and most national numbers do not require local address. The portal flags which ranges need verification before purchase.

Porting in from another UK provider

Paperless LNP is supported for ranges from most UK carriers. The process needs the current bill, the account holder details, and the list of numbers. Typical port window is 5–10 working days. Numbers continue working on the old carrier until the cutover.

SIP setup

UK numbers can be delivered over a didlogic SIP trunk with inbound and outbound on the same connection, including native CLI presentation. Trunk auth is by IP or by credentials. Codec support includes G.711 a-law (UK standard), G.711 µ-law, G.722, and Opus.

SMS on UK numbers

UK mobile 07 supports full inbound and outbound SMS, suitable for verification flows, OTPs, and conversational use cases. UK geographic (020, regional), UK 0800 and UK national 03 do not support SMS today.

Compliance

FAQ

How can I get a UK virtual phone number?

Sign up for a free didlogic account, open the Numbers tab in the portal, and pick a UK number by area code or city. London 020, regional numbers, 0800 freephone, and UK mobile are all available. Most activate within 8 hours.

Is there a free UK virtual phone number?

didlogic offers a free trial for testing, but free-forever UK numbers are rare and usually come with hidden costs (incoming-call limits, app-only access, or shared numbers). For business use, a paid number with a fixed monthly fee is the standard, with prices starting at $2 / month on didlogic.

Can I keep my UK number when changing providers?

Yes. UK numbers can be ported between providers under Ofcom rules. didlogic supports paperless LNP for most UK ranges with a typical 5–10 working day port window and no downtime during the cutover.

What's the difference between 020, 0203, 0207, and 0208?

All four are London geographic numbers. 020 is the actual London area code. 0207, 0208, and 0203 refer to the next digit after 020, which historically identified different sub-areas of London (0207 inner, 0208 outer, 0203 newer allocations). For dialling and call handling they are identical — the formal area code is 020 in every case.

Can I get an Ofcom-registered UK number?

didlogic operates within Ofcom rules for UK voice and number assignment. Numbers from didlogic are sourced from UK-licensed operators and follow UK numbering plan requirements.

Do you provide UK 0800 freephone numbers?

Yes. UK 0800 and 0808 freephone numbers are available with inbound routing rules, time-of-day forwarding, and the option to switch destination without changing the public number. Calls to 0800 are free for UK callers from both landlines and mobiles.

Can I use a UK number with Asterisk, FreeSWITCH, or 3CX?

Yes. didlogic provides UK numbers over standard SIP trunking compatible with Asterisk, FreeSWITCH, 3CX, Cisco CUCME, Avaya, and any other SIP-based PBX. Setup guides for each are available in the docs.

Can I use a UK number with Vapi, Retell, ElevenLabs, or LiveKit?

Yes. didlogic provides SIP termination for Vapi, Retell, ElevenLabs, LiveKit, Bland AI, and Synthflow. UK numbers can be assigned to the same SIP trunk that carries AI voice traffic, so a UK 020 or regional CLI is presented on outbound bot calls.

How long does activation take?

Standard UK numbers activate within 8 hours. Ranges that need address verification can take up to 48 hours. Porting from another provider typically takes 5–10 working days.

Do UK virtual numbers work for SMS verification (WhatsApp, banks)?

UK mobile numbers (07) from didlogic accept inbound SMS, which covers most verification use cases including WhatsApp Business, Telegram, and many fintech onboarding flows. They also support outbound SMS for sending OTPs. UK geographic (020, 0161, others), UK 0800 and UK national 03 do not support SMS today.
