Area Code 3533 – Bata

Overview of Area Code 3533 (Bata, Bulgaria)

Area code 3533 is a geographic National Destination Code (NDC) within the Bulgarian numbering plan, assigned to the town of Bata and its surrounding localities. Bata is situated in the Burgas Province, southeastern Bulgaria, and falls under the administrative jurisdiction of the Pomorie Municipality. The code serves the fixed-line PSTN (Public Switched Telephone Network) and VoIP services registered to this specific geographic area.

Geographic Coverage and Administrative Context

The 3533 area code covers Bata and nearby settlements within the Pomorie Municipality. This includes villages and smaller communities that rely on the local telephone exchange. The region is part of the Burgas agglomeration, though it maintains a distinct local dialing area. The code is allocated exclusively for fixed-line services, meaning that mobile numbers in Bulgaria use non-geographic prefixes (e.g., 87, 88, 89) and are not affected by this area code.

Dialing Formats and Instructions

For callers within Bulgaria, the national trunk prefix is 0. To call a Bata number from another Bulgarian city, dial: 0 3533 [subscriber number]. For example, if the local subscriber number is 12345, the national format would be 03533 12345.

For international callers, the country code for Bulgaria is +359. The leading zero of the area code is dropped. Therefore, from abroad, dial: +359 3533 [subscriber number]. Using the same example, the international format would be +359 3533 12345.

Numbering Structure and Overlays

Bulgarian geographic numbers typically consist of the area code followed by a subscriber number of varying length. In the 3533 area, subscriber numbers are generally 4 to 5 digits long, making the total national significant number (NSN) length 8 or 9 digits, excluding the trunk prefix. As of the latest ITU-T E.164 guidelines, Bulgaria does not currently have overlay codes for this region; the 3533 code remains the sole geographic identifier for Bata. However, number portability allows subscribers to retain their numbers when switching between fixed-line operators, but the geographic association remains tied to the original exchange.

Practical Guidance for Callers

• Local callers within Bata: In many cases, local calls can be made using only the subscriber number without the area code, depending on the operator's dialing plan. However, for reliability, it is recommended to always use the full national format.
• National callers from other Bulgarian regions: Always include the trunk prefix and area code: 0 3533.
• International callers: Use the plus sign (+) or the international access prefix of your country, followed by 359, then 3533, and the subscriber number. Omit the leading zero.
• VoIP and mobile users: When dialing from VoIP services, follow the same international or national format as appropriate. Ensure that your service provider supports calls to Bulgarian geographic numbers.

Understanding the correct dialing format is essential for both residential and business communications. Whether you are contacting a local business in Bata or a resident, using the proper prefix ensures your call is routed efficiently through the Bulgarian PSTN.
