Your ZIP codes will be listed here.
iAbout this map: boundaries are U.S. Census Bureau ZIP Code Tabulation Areas, which closely approximate USPS delivery areas but are not exact. PO Box-only and single-business ZIP codes have no delivery area, so they do not appear. Household counts are 2020 Census housing units and are estimates only. City names come from GeoNames postal data (CC BY 4.0) and use each ZIP code’s main USPS city name. For exact mailable counts, request counts or call 800.723.5254.

Plan your event with confidence

In-Home Date Calculator

Work forward from your order date, or backward from your event date, to see when your mail drops, when it reaches mailboxes, and how it lines up with your event.

Your Order

All estimates count business days (Mon–Fri), skipping federal holidays.

Approximate Mail Date

iHow it’s calculated: 3 to 5 business days after your order date. This covers list processing, printing, and mail preparation before your pieces enter the USPS mail stream.

Approximate In-Home Date

First Class

Bulk (Marketing Mail)

iHow it’s calculated: First Class adds 5 business days to the mail date range. Bulk mail travels at a lower USPS priority, so it adds 10 business days, or 14 business days when mailing during peak periods (Sep 26–Oct 10 for Medicare AEP and election mail, and Thanksgiving through Christmas for holiday mail). Actual delivery varies by region and season. These are projected dates based on USPS advertised delivery times and are not guaranteed.

Ideal Date Range for Events

If Mailing First Class

If Mailing Bulk

iHow it’s calculated: 10 business days after each in-home date range. This gives recipients time to receive your mailer, plan around it, and RSVP before your event.

If Mailing First Class

If Mailing Bulk

iHow it’s calculated: counted back from your event date: 10 business days before the in-home date, then 5 business days (First Class) or 10 business days (Bulk; 14 during peak periods) for delivery, then 5 business days for processing. This is the latest date to order; ordering earlier gives you more breathing room.

Approximate Mail Date

First Class

Bulk (Marketing Mail)

iHow it’s calculated: 3 to 5 business days after the order-by date above. This covers list processing, printing, and mail preparation before your pieces enter the USPS mail stream.

Approximate In-Home Date

iHow it’s calculated: First Class adds 5 business days to its mail date range; Bulk adds 10, or 14 during peak periods (Sep 26–Oct 10 and Thanksgiving through Christmas). Because Bulk is ordered and mailed earlier, both arrive about 10 business days before your event. Actual delivery varies by region and season. These are projected dates based on USPS advertised delivery times and are not guaranteed.
