ZIP Code In White Rock Changes July 1

USPS News:

In order to provide efficient and cost-effective mail delivery now and for the future, the U.S. Postal Service is creating a new ZIP Code in the White Rock area, effective July 1, 2016.

The new ZIP Code is 87547.

The new White Rock ZIP Code 87547 impacts some addresses in the current Los Alamos 87544 ZIP Code area. The new ZIP Code’s northern boundary is just south of land occupied by the Los Alamos National Laboratory. 

This week, all postal customers who will be affected by these changes are being notified by mail. If a customer does not receive written notification by the end of this week, they are NOT affected by these changes.

The change comes in preparation for future growth in the area and to continue to provide efficient delivery service for Los Alamos and White Rock postal customers.

The Postal Service encourages affected customers to use their new ZIP Code and notify family, friends, business customers and business associates beginning July 1; however, mail with either ZIP Code will be delivered for one year following the change. Individuals should include their new ZIP Code on any reply mail where the sender requests updated or corrected address information.

Customers in the affected area should also use their new ZIP Code when reordering stationery such as letterhead, envelopes, promotional literature, forms, and business cards.

No other action is necessary on customers’ part, as magazine publishers, financial institutions, insurance companies and utilities typically use computerized customer mailing lists, which update address ZIP Codes on a regular basis.

The Postal Service receives no tax dollars for operating expenses and relies on the sale of postage, products and services to fund its operations.

Description of boundaries for new White Rock 87547 ZIP Code:

  • Northern: Running West to East from Sandoval County alignment, following southern extents of lands designated as Los Alamos National Laboratory to intersection with Santa Fe County alignment.
