The unified civil number (Bulgarian: Единен граждански номер, ЕГН, romanized: Edinen grazhdanski nomer, EGN) is a 10-digit unique number assigned to each Bulgarian citizen. It serves as a national identification number. An EGN is assigned to Bulgarians at birth, or when a birth certificate is issued. The uniform system for civil registration and administrative service of population (Bulgarian: Единна система за гражданска регистрация и административно обслужване на населението; abbreviated: ЕСГРАОН, ESGRAON) regulates the EGN system.
The initial six digits correspond to the birth date. The first two digits are the last two digits of the year, and the last two digits are the day of the month. For people born between 1900 and 1999 the middle digits are the month number: YYMMDD. For people born before 1900, 20 is added to the month: YY M+20 DD. For people born from 2000, 40 is added to the month: YY M+40 DD.
The next three digits designate the birth order number, the third digit being even for males and odd for females. Each district is assigned a range of three-digit numbers, used consecutively, altering even and odd numbers between males and females born on the particular day. In rare cases a district may not have enough numbers, so numbers are "borrowed" from an adjacent district.
A check digit, calculated from the nine digits using the following algorithm, is appended: 1 Each digit is multiplied by its weight; the weight for the nth digit is 2n modulo 11:

Examples
Calculation
The first female registered born on 2 January 1975 has number 75 (1975) 01 (January + 0) 02 (2nd) 001 (district has numbers, say, 0-50, and this is first female of this date) & check digit, i.e. 750102001 & check digit. 7x2 + 5x4 + 0x8 + 1x5 + 0x10 + 2x9 + 0x7 + 0x3 + 1x9 = 52; divide by 11, (quotient is 4, ignore), remainder 8 is check digit. So EGN is 7501020018.
Valid EGN numbers
7523169263 — a male, born on 16 March 1875
8032056031 — a female, born on 5 December 1880
8001010008 — a male, born on 1 January 1980
7501020018 — a female, born on 2 January 1975
7552010005 — a male, born on 1 December 2075
7542011030 — a female, born on 1 February 2075
Misuse
In order to easily cross borders criminals have been known to change EGNs. There were 46 such cases detected in March 2005.
Using the EGN system for identification raised some privacy concerns, though they are officially considered personal information and are protected by law.
