Mongolia Vehicle State Plate-Number Reservation

Fields

• province enum required

  The province (aimag) or the capital, Ulaanbaatar, whose currently available plate-number inventory the applicant is browsing and reserving from. Each province currently issues from one active 3-letter plate series.

  enum: 22 values

  The weekday on which the reserved plate must be collected/finalized, determined by which column of the availability grid the applicant's chosen plate number appears under.

• plateSeriesAndNumber string required

  The specific state plate number being reserved, chosen by clicking one available button in the province's availability grid (not typed free text). The 3-letter prefix is the province's currently active plate series (rotates over time as series are exhausted); the 4 digits are the specific number picked.

  Whether the plate is being reserved by an individual, an organization (legal entity), or a foreign citizen. Determines which of the three registration-number field groups below applies.

  pattern
• foreignCitizenIdentityNumber string optional

  The foreign-citizen applicant's identity/passport number. Required only when registrantCategory is foreign. The source form imposes no visible format constraint (a plain free-text box, no maxlength/pattern attribute), so this schema does not invent one beyond a minimum length.

  length: 1–30
• vehicleFrameNumberLast5 string required

  The last 5 characters (digits and/or Latin letters) of the vehicle's own frame/chassis number, binding this plate reservation to a specific vehicle. Required for every registrant category.
