This page describes the different message format types in use by states offering an Electronic Liens and Titles program. We’ll look particularly at what states are currently doing.
The following file formats are currently in use:
- The AAMVA ELT message format. AAMVA’s format for ELT message exchange is a subset of their general message exchange format. See the section below for more details.
- Fixed Length, single format. All messages adhere to a single file format type. Message records are fixed length and are proprietary to each state.
- Fixed Length, multiple formats. Each transaction has a separate file format defined. Message records are fixed length and are proprietary to each state.
This explains how messages are grouped together for delivery to the partner:
- Not grouped. Messages are sent individually.
- Plain text file. Messages are added to a text file and sent together.
- Batched. A file containing the messages also contains a header and/or footer record to batch the messages. Frequently used to indicate the total number of messages included.
Evaluation of Practices by State
|California||Fixed Length, multiple formats||Plain text file|
|Florida||Fixed Length, multiple formats||Batched||As part of the lien notification record, owner records are sent separately. This allows for flexibility in the number of owner records that can be included. File headers are used to verify message totals and confirm receipt. Inherent in Florida’s file format is a resend indicator when confirmation of receipt not received by the state.|
|Georgia||Fixed Length, single format||Batched||Proprietary flat-file format.|
