Buy UK Phone Numbers Online
AVOXI offers four UK virtual phone number types, each available for immediate online purchase with fast activation and integration-ready setup for call forwarding, IVR, and inbound call handling.
Toll-Free (0800)
0800 numbers are free for callers in the UK and remain the standard for customer service teams, support operations, and businesses that want to present an accessible, nationwide presence.
TrueLocal Caller ID
Two-way inbound and outbound phone numbers with guaranteed local caller ID — helping drive higher answer rates and making it easier to connect with customers across the UK.
National (03)
Non-geographic numbers billed at the same rate as standard geographic calls, even from mobile. Widely used by businesses, charities, and public sector organizations that want a consistent national presence without the perception of premium-rate pricing.
Local DID
(Direct Inward Dialing)
Geographic numbers carrying familiar area codes for London, Manchester, Birmingham, Edinburgh, Leeds, and more. Ideal for businesses that want a credible local presence in specific UK markets. Numbers labeled TrueLocal guarantee your local caller ID displays during outbound calls.
UK Local DID Numbers
A local UK phone number does more than just route calls — it signals to customers that you're present, accessible, and operating in their market. For businesses that want to compete seriously in cities like London, Manchester, or Birmingham, a local DID with the right area code is one of the quickest ways to establish that credibility.
The UK uses the country code +44. Within the UK, geographic area codes include 020 for London, 0161 for Manchester, 0121 for Birmingham, 0131 for Edinburgh, and 0113 for Leeds. Each number carries the familiar local prefix UK customers expect, making your business feel local even if your team is based on the other side of the world.
All local DID numbers can be configured to forward calls to any device or team globally, and TrueLocal-designated numbers go a step further — guaranteeing that your outbound calls display the same local number your customers know, rather than an unfamiliar international line. For businesses searching for a virtual telephone number in the UK, local DID service is often the most direct option.
UK Toll-Free Numbers
0800 numbers have long been the benchmark for accessible, customer-first businesses in the UK. Offering a toll-free line tells customers that reaching you costs them nothing — a small but meaningful signal that matters when first impressions count. Since 2015, 0800 calls have also been free from mobile phones, removing a historic barrier that once discouraged callers from using toll-free lines.
AVOXI's UK 0800 toll-free numbers are provisioned through licensed UK carrier relationships and can be routed to any team or destination worldwide. They're well-suited to inbound customer service operations, support desks, and sales lines where call volume is high, and caller experience is a priority.
Every number is provisioned through UK telecom relationships and built to support high inbound call volumes across the UK telecom environment.
Two-Way Local Caller ID & PSTN Replacement for the UK
The UK's telecom market is one of the most mature in the world, but traditional PSTN infrastructure still carries the constraints that legacy voice systems are known for — rigid pricing, limited scalability, and minimal insight into how calls are actually performing. For businesses managing significant outbound call volume into the UK, those constraints add up quickly.
AVOXI's SIP-based platform replaces that overhead with a cloud-native alternative that's easier to manage, more cost-efficient, and designed for teams that need to operate at scale. At the center of the outbound experience is TrueLocal, which ensures every call your team places to a UK customer displays a consistent, city-specific local number — rather than an anonymous international line. UK consumers are increasingly unlikely to answer calls from numbers they don't recognize; local caller ID directly addresses that friction.
The same TrueLocal number that handles outbound calls also receives inbound callbacks, so customers always have a familiar point of contact. For account management teams, field sales representatives, and customer success operations working relationships across London, Manchester, Edinburgh, and beyond, that consistency builds trust that's hard to manufacture any other way.
Moving off traditional PSTN lines also means gaining full visibility into your voice operation. AVOXI's platform provides real-time monitoring of latency, jitter, and packet loss, with all traffic running over Tier 1 networks, delivering a 4.49+ MOS score. Call routing, number management, and quality reporting are all centralized in one platform — helping reduce carrier complexity while supporting alignment with the UK telecommunications framework.

Key Regulations for Voice Services in the United Kingdom
Telecommunications services in the UK are regulated by Ofcom under the Communications Act 2003. Ofcom sets the rules for how voice services — including VoIP and virtual numbers — are provisioned, used, and managed within the UK.
Regulatory Overview
VoIP is legal in the UK for both business and consumer use. Providers of public electronic communications networks and services are generally governed by Ofcom’s General Conditions of Entitlement, which include requirements covering number portability, access, and consumer protections. AVOXI operates through UK carrier partners working within this framework.
Key Compliance Requirements
General Conditions of Entitlement: Providers of public electronic communications networks and services in the UK must comply with Ofcom’s General Conditions, which cover matters including number use, portability, access, and consumer protections.
Telephone Preference Service (TPS/CTPS): Businesses conducting live marketing calls in the UK should screen consumer numbers against the TPS and business numbers against the CTPS where applicable. They should also maintain their own internal do-not-call list for anyone who objects to receiving calls. Violations are subject to enforcement action by the Information Commissioner's Office (ICO).
Calling Line Identification (CLI) Rules: Ofcom requires that outbound calls display an accurate caller ID. Misrepresenting or spoofing the CLI is prohibited. AVOXI's TrueLocal service is fully compliant with UK CLI requirements.
Emergency Call Access: UK voice providers must ensure end users can access emergency services (999 and 112) from virtual numbers, in accordance with Ofcom's emergency call obligations.
Number Portability: The UK supports full fixed-line and mobile number portability. Porting requests follow Ofcom-prescribed procedures and are processed through AVOXI's licensed carrier partners at no cost to the customer.
UK GDPR & Data Protection Act 2018: Businesses handling customer data through voice communications must comply with the UK General Data Protection Regulation (UK GDPR) and the Data Protection Act 2018, including lawful collection, secure storage, and appropriate use of personal information.
Privacy and Electronic Communications Regulations (PECR): PECR governs the use of electronic communications for marketing purposes, including SMS sent via virtual numbers. Businesses must ensure recipients have appropriate consent and that opt-out mechanisms are clearly provided.
Call Record Retention: Businesses subject to industry-specific regulations — including financial services (FCA), healthcare (CQC), and legal sectors — should retain call records in accordance with their applicable compliance obligations and Ofcom guidelines.
AVOXI & UK Regulatory Compliance
All UK virtual numbers provided by AVOXI are provisioned through Ofcom-compliant carrier partners and meet applicable UK telecommunications law. AVOXI's team can walk you through the documentation process and help you navigate any specific compliance requirements relevant to your industry or use case.
