Notice of Landbase Map Object Change Freeze

The Member Mapping application will be unavailable during our annual Landbase map maintenance, part of our ongoing effort to keep maps current.

 MAINTENANCE DATES (Eastern Standard Time):

     Map Update Freeze BEGINS – Thursday, December 9, 2021 (2359)

     Map Update Freeze ENDS – Monday, January 3, 2022 (an email will be sent)

Beginning December 9th at 2359, access to update map objects and services will be temporarily frozen. This means both the “Member Mapping” and the “Member Mapping - Upload your map data” applications will not be available.

If a notification area needs to be added during the freeze, it will be necessary to revert to municipal level notification until after the Landbase maps are active again on January 3, 2022.

This maintenance is critical because the Landbase map data is used by members as reference points when designating facility notification areas, and by both web ticket entry users and customer service reps when drawing excavation notification areas. Both the facility notification areas and the ticket entry maps are used to determine which locate requests / tickets are sent to each Mapped Member.

If you have any questions, please contact Member Services at or 412-464-7168 or 800-248-1786 ext. 7168.

Thank you for your patience as we update our Landbase maps.


Pennsylvania 811 is pleased to announce the release of a new Response “notes” feature. Please take advantage of additional information sharing that Response notes field can offer.

  • Response notes are optional and limited to 280 characters.
  • Notes are accepted, saved for viewing with each response in our online applications, and shared with the excavator.
  • The content added to a note will not change the Act 287 as amended requirement to post a FINAL response to a ticket. The field is meant to convey additional information such as mark out detail or other information for the excavator.

For help, please email or call 1-800-248-1786 x 7168.
