EMBS (Единствен матичен број на субјектот) is the unique master number assigned to every registered legal entity by the Central Register of North Macedonia. It identifies the company across tax, court, and statistical systems and is required on filings to the UJP (Public Revenue Office).

How many digits is an EMBS?

An EMBS is 7 digits. The first six form the sequential base number and the seventh is a check digit derived from them with a weighted modulo-11 algorithm.

How is the check digit calculated?

Each of the first six digits is multiplied by a descending weight (7, 6, 5, 4, 3, 2). The products are summed, the sum is reduced modulo 11, and the check digit is 11 minus that remainder. A remainder that yields 11 maps the check digit to 0; a result of 10 indicates the base number does not form a valid EMBS.

Is the EMBS the same as the tax number?

No. The EMBS is the company registration master number from the Central Register, while the tax number (ЕДБ, used for VAT) is a separate 13-digit identifier issued by the UJP. They often appear together on Macedonian documents but serve different systems.

Is my EMBS uploaded anywhere?

No. Validation runs entirely in JavaScript inside your browser. Nothing is transmitted, logged, or stored, and the tool works offline once loaded.

North Macedonia EMBS at a glance

The EMBS (Единствен матичен број на субјектот — “unique master number of the entity”) is the registration number that the Central Register of North Macedonia assigns to every company and legal entity. It is the backbone identifier across court, statistical, and tax systems, and is required on filings to the UJP (Public Revenue Office). The EMBS is 7 digits, with the last digit acting as a check digit.

How it works

The check digit protects the first six digits with a weighted modulo-11 scheme:

weights = [7, 6, 5, 4, 3, 2]
sum     = Σ (digit[i] * weight[i])   for i = 0..5
rem     = sum mod 11
check   = 11 - rem
  if check == 11 → check = 0
  if check == 10 → base number is INVALID (no single check digit)

The computed check must equal the seventh digit. Modulo-11 weighting catches every single-digit substitution and most adjacent transpositions — the typical errors when an EMBS is keyed in by hand.

Tips and example

For base 123456, the weighted sum is 1·7 + 2·6 + 3·5 + 4·4 + 5·3 + 6·2 = 7 + 12 + 15 + 16 + 15 + 12 = 77. 77 mod 11 = 0, so check = 11 − 0 = 11 → 0. A valid EMBS would therefore be 1234560. A correct check digit only proves the number is well-formed — verify the entity itself in the Central Register before relying on it.
