Since GEO2_MX maintains consistent boundaries across samples, it was necessary for us to combine some municipalities. As a result, it is not possible to directly match these harmonized codes to a non-IPUMS data source. I have attached a crosswalk between GEO2_MX and the sample-specific municipality codes. This should assist you in merging with National Statistic Office codes.
Please see this previous answer for information on the 2016 data release.
Hope this helps.
