Local caller ID in Bulgaria
Bulgaria's outbound calling environment is challenging for foreign numbers. Called parties in Sofia, Plovdiv, and Varna dismiss international prefixes with near-zero answer rates; a local 02 (Sofia) or 032 (Plovdiv) number on the caller ID is often the difference between a conversation and an ignored call. UnlimCall provisions a genuine Bulgarian geographic DID for your account at onboarding. The number is registered in-country, presents a native prefix to the Bulgarian PSTN, and routes through UnlimCall's edge before terminating locally. Unlike a shared number pool, your DID is exclusive to your account — its reputation is shaped by your team's calling patterns, not contaminated by other customers.

Number types & setup
Bulgaria uses a geographic numbering plan where the area code reflects the city or region. Sofia (02) is the highest-trust prefix for national campaigns. Plovdiv (032), Varna (052), Burgas (056), and Stara Zagora (042) are available for region-specific targeting. National non-geographic ranges may be available for certain campaign types; discuss your requirements with your account manager. All DIDs are included in the flat seat price — no separate per-number charge applies.
Regulatory notes
Outbound calling in Bulgaria is subject to the Electronic Communications Act (Закон за електронните съобщения) and enforcement by the Commission for Consumer Protection (КЗП) and the Communications Regulation Commission (КРС). Bulgarian law places obligations on commercial callers regarding identification and consent; using a genuine locally registered number that accurately reflects your calling entity may be relevant to your compliance posture. Consider reviewing CRC guidance and consulting legal counsel familiar with Bulgarian telecommunications law before launching consumer-facing campaigns.
The math
A 25-agent team on UnlimCall pays a fixed $3,725/mo (25 × $149). On per-minute billing, 25 agents dialling 10,000 minutes each at ~$0.0085/min costs $2,125/mo — but at 17,500 minutes per agent the per-minute bill reaches $3,719 and continues to climb. Break-even versus a $0.0085 per-minute rate sits at roughly 11,650 minutes per agent per month. BPO floors running Bulgarian campaigns with back-to-back dialling typically reach 18,000–22,000 minutes per agent per month, putting them well past break-even.
Frequently Asked Questions
Is a Sofia number effective for campaigns targeting other Bulgarian cities? A Sofia (02) number is recognised nationally and performs well for broad Bulgarian campaigns. If your campaign is heavily focused on a specific region, a matching regional prefix (for example, 032 for Plovdiv) can improve local trust further. Both options are available at onboarding.
How does UnlimCall route Bulgarian calls? Traffic originates from your SIP infrastructure, passes through the nearest UnlimCall POP, and terminates onto the Bulgarian PSTN via in-country interconnects. This keeps audio latency below 50ms and ensures the caller ID presents as a native Bulgarian number.
Can I port an existing Bulgarian number to UnlimCall? Number porting availability in Bulgaria depends on the originating carrier and current regulatory processes. Contact your account manager during onboarding to discuss porting options for an existing DID.
