The cost of a postcard stamp in 2019: core facts
In 2019, the cost of a postcard stamp in the United States was 35 cents for a single, rectangular postcard that met standard size and weight requirements. This rate reflected a steady, measured approach from the US Postal Service (USPS), which had maintained the postcard category as the lowest-priced class of mail for many years. Understanding this rate requires distinguishing postcards from letters and large envelopes, because each has different pricing rules and design expectations. Below we outline the verified details, how the 35‑cent postcard stamp compared with other mail options, and why these prices matter for senders who rely on physically addressed mail.
What the US Postal Service defines as a postcard
The USPS specifies precise dimensions and characteristics for a piece to be sold and mailed as a postcard. These rules affect price, handling, and deliverability. Meeting postcard criteria keeps costs low compared with letters, which require additional processing steps such as envelope folding and more complex automation.
Key specifications in 2019 (postcard)
A card must be rectangular, within a defined size range, and weigh within limits to qualify as a postcard and use the 35‑cent stamp rate.
| Attribute | Verified Detail (2019) | Source Type |
|---|---|---|
| Minimum size | 3.5 in x 5 in (89 mm x 127 mm) | USPS Standards |
| Maximum size | 6 in x 4.25 in (152 mm x 108 mm) | USPS Standards |
| Minimum thickness | 0.007 in (0.18 mm) | USPS Standards |
| Maximum thickness | 0.025 in (0.64 mm) | USPS Standards |
| Weight limit | 1 oz (28.35 g) or less | USPS Standards |
| Delivery timeframe | Typically 2–3 days for domestic, faster for priority | USPS Service Standards |
When a piece falls within these ranges and is not addressed to a specific individual inside an envelope, it is classified as a postcard. This classification is important because it qualifies the item for the lower postcard rate, which in 2019 was satisfied by a 35‑cent stamp. Deviations such as using an envelope, adding extra services, or exceeding size or weight limits can change the price category and increase the cost.
Postcard stamp cost in 2019: context and comparisons
The 35‑cent postcard stamp in 2019 was intentionally kept lower than the price of a First-Class Letter stamp to encourage use of smaller, lightweight mail. This pricing structure helps manage mail volume and processing complexity. For senders, choosing a postcard often meant faster automated processing and lower total cost per piece, especially for straightforward communications such as event announcements or brief business updates.
Cost comparison: postcard vs letter vs large envelope (2019)
- Postcard (3.5" x 5" to 6" x 4.25", 1 oz): 35 cents using a postcard stamp, the lowest standard domestic rate for a addressed item.
- First-Class Letter (1 oz): 55 cents for a rectangular envelope, higher than the postcard rate due to additional processing and flexibility in format.
- Large Envelope (Flats): Started at a higher base rate with potential discounts for presort and automation, typically above 35 cents for similar-weight items.
These differences highlight why senders chose postcards for simple, direct mailings. The 35‑cent postcard stamp in 2019 offered a predictable, budget-friendly option with reliable delivery within standard service timeframes.
How postcard pricing fits into long‑term USPS trends
Postcard pricing has historically been stable, with adjustments occurring less frequently than for letters. In 2019, the USPS maintained this stability as part of a broader strategy to support efficient, low-cost channels of mail. Understanding this longer-term pattern helps senders anticipate future rates and plan mailing budgets with confidence.
Practical implications for senders in 2019
For businesses and individuals using postcards in 2019, the 35‑cent stamp offered a predictable way to reach customers and constituents. Common use cases included event invitations, brief updates, and marketing announcements where a full envelope was unnecessary. Because postcards are handled more quickly in automated systems, they often delivered faster than letters, adding value beyond just the stamp price.
Key considerations when using postcard stamps in 2019
- Confirm the piece fits official postcard dimensions; otherwise it may be charged at a higher letter or flat rate.
- Use a dedicated postcard stamp, or a regular first-class stamp if a postcard stamp is unavailable, but expect the price difference if the item is technically a postcard.
- Plan for delivery expectations; postcards typically arrive within 2–3 days for standard domestic service.
- Check for additional services (e.g., Certified Mail or Tracking) that may require extra fees beyond the base stamp.
