Back end address checking
A batch product verifies an address at the back end, typically after the address has entered the company's database. Essentially, the tool will go through and standardize addresses to the USPS® format while simultaneously making corrections to inaccurate entries. For example:
| Before Batch | Action taken | After Batch |
| 1801 North Main Road, Lee, MA, 01238 | Standardized to USPS format, added ZIP + 4® | 1801 N Main Rd, Lee, MA, 01238-9063 |
| 36 Fletcher Avenue, Lexington, MA, 02421 | Standardized to USPS format, fixed incorrect ZIP™ and added ZIP + 4 | 36 Fletcher Ave, Lexington, MA, 02420-3720 |
| 1900 Main St., Atlanta, GA, 30318 | Address is flagged as unfixable because a post-directional is needed. There are 6 Main Streets in Atlanta, and batch doesn't know which one this is | Unfixable |
These are just a sample of the many actions a batch tool can take. Generally, batch products are used to maximize the postal discounts for bulk mailers, but they have many limitations. In order to achieve the highest degree of address data quality possible, a company must employ a rapid addressing tool in coordination with a batch product.
