By default generates 13 sign ean code in format 1234567890123 You can pass 8 to generate ean8 code
# File lib/faker/code.rb, line 19 def ean(base = 13) base == 8 ? generate_base8_ean : generate_base13_ean end
isbn(base = 10)
click to toggle source
By default generates 10 sign isbn code in format 123456789-X You can pass 13 to generate new 13 sign code
# File lib/faker/code.rb, line 13 def isbn(base = 10) base == 13 ? generate_base13_isbn : generate_base10_isbn end
npi()

Generates a 10 digit NPI (National Provider Identifier issued to health care providers in the United States)
# File lib/faker/code.rb, line 7 def npi Random.new.rand(10 ** 10).to_s.rjust(10, '0') end
nric(min_age = 18, max_age = 65)

By default generates a Singaporean NRIC ID for someone who is born between the age of 18 and 65.
# File lib/faker/code.rb, line 31 def nric(min_age = 18, max_age = 65) birthyear = Date.birthday(min_age, max_age).year prefix = birthyear < 2000 ?
