== Accepted codes for National proof data (file300/700): ==
=== Accepted codes for type of proof: ===
 . '''00 '''(unknown);
 . '''11''' (based on first crop sampling daughters);
 . '''12''' (based on first and second crop daughters);
 . '''13''' (based on parent average and genomic information only);
 . '''21'''(based on imported semen of proven bull, second crop daughters only);
 . '''22''' (based on mostly, more than 50%, imported daughters or daughters born from imported embryos.)
 . '''23''' (GEBV with foreign PA)
 . '''24''' (GEBV with foreign proof)

=== Accepted abbreviations for publication of proof: ===
 . '''Y''' (if bull proof meets national standards for official publication in the country sending information.);
 . '''P'''  (if bull is part of a simultaneous progeny-testing program, but the  proof does not yet meet national standards for official publication);
 . '''N''' (otherwise).

=== Accepted codes for status of bulls: ===
 . '''00'''(unknown);
 . '''10'''(bull randomly sampled through an official AI scheme);
 . '''15''' (young bull, genomically tested, not yet selected for AI);
 . '''20'''(other bull. Records with “20” in this file will be excluded from the international evaluation, unless type of proof is “21”).

== Accepted codes for National parameter data (file301/701): ==
=== Reference (genetic) base definition in the country sending information: ===
 . breed initial (1 char),
 . year established (YY),
 . bull(b) or cow(C) (1 char);
 . birth(B), calving (C) or evaluation (E) (1 char);
 . year of event (use middle year if base on multiple year (YY);

for breed initial see breed codes in https://interbull.org/ib/icarbreedcodes (use X If based on multiple breeds) Example: H00BB95 means a base defined 2000 based on Holstein bulls born in 1995.
