9 FAM 41.113 PN1 INFORMATION ABOUT THE MACHINE READABLE VISA (MRV)
The information on the MRV is printed on an adhesive foil and consists of five sections that:
Reflect the applicant’s biographic data;
Contain information about the visa itself (visa type, number of entries, date of issuance, and date of expiration);
Show the 88-character field used for annotating additional information about the recipient, when necessary; (e.g., annotation of a petition number, SEVIS number, etc.);
Display a digitized photo of the visa recipient; and
Contain a machine-readable zone (MRZ) consisting of two lines of highly sensitive coded data. Scanners connected to authorized computer networks can read the data located in the MRZ and instantly recall records associated with the MRV. Damage to either line may prevent the scanner from reading the data, requiring manual data-entry before processing, which could lead to delays at ports of entry. You should instruct MRV recipients to take care with their MRVs, avoiding folding the foil, and preventing contact between the foil and objects that could damage it, such as paper clips, staples, etc.
