USPS Non Machinable Stamps sets the stage for this enthralling narrative, offering readers a glimpse into a story that is rich in detail, brimming with originality from the outset.
When the United States Postal Service (USPS) introduced the non-machinable stamp, it marked a significant shift in the way postal services handled packages. For those unfamiliar, non-machinable stamps are a type of postage that is not designed to be processed by automated machines. These stamps are typically used for packages that are bulky, irregularly shaped, or contain items that cannot be easily handled by automated machinery.
What is a Non-Machinable Stamp?: Usps Non Machinable Stamp

A Non-Machinable Stamp, also known as a non-machineable or NMS stamp, is a type of postage stamp issued by the United States Postal Service (USPS). It is specifically designed for mail pieces that cannot be processed by automated machines.
The main purpose of a Non-Machinable Stamp is to indicate to postal workers that the mail piece cannot be sorted or processed by automated machinery. This is often due to the unique shape, size, or material of the mail piece, which makes it difficult for machines to read the barcode or sort it properly. As a result, the mail piece must be handled manually, which can increase the processing time and cost.
Types of Mail Pieces that Require Non-Machinable Stamps
The USPS requires a Non-Machinable Stamp for mail pieces that are irregularly shaped, oversized, or excessively heavy. These include:
- Irregularly shaped packages: Packages with unusual shapes or dimensions, such as a box with a rounded corner or a bag with an irregular opening.
- Oversized packages: Packages that exceed the standard dimensions for regular mail service, such as a large box or a package with excessive width or height.
- Excessively heavy packages: Packages that weigh more than the standard weight limit for regular mail service, such as a large package with a high amount of weight.
Mail pieces that require a Non-Machinable Stamp must be marked with a distinct “Non-Machinable” sticker or label, which alerts postal workers to handle the mail piece manually.
Requirements for Using Non-Machinable Stamps
To use a Non-Machinable Stamp, the mail piece must meet specific requirements. These include:
- The mail piece must be marked with a “Non-Machinable” sticker or label.
- The mail piece must be properly addressed with a legible and complete address.
- The mail piece must be affixed with the correct postage for the destination, as well as any applicable fees or surcharges.
If a mail piece fails to meet these requirements, it may be rejected or returned to the sender, or even held at the post office for manual processing.
Advantages and Disadvantages of Using Non-Machinable Stamps
Using a Non-Machinable Stamp has both advantages and disadvantages. The advantages include:
- Ensuring manual handling of mail pieces that cannot be processed by automated machines.
- Providing a clear indication to postal workers of the need for manual handling.
However, the disadvantages include:
- Increased processing time, which can result in delayed delivery.
- Additional costs associated with manual processing and handling.
In conclusion, the Non-Machinable Stamp plays a crucial role in ensuring that mail pieces are processed accurately and efficiently. By understanding the requirements and advantages of using a Non-Machinable Stamp, senders can avoid potential issues and ensure timely delivery of their mail pieces.
Eligibility for Non-Machinable Stamps
Eligible items that cannot be processed by automated machinery at the Postal Service facilities may use non-machinable stamp requirements when mailed. In most cases, a non-machinable stamp is required if the item is oversized, irregularly shaped, or has a special handling requirement.
Package Requirements
Packages that need to be checked by a mail handler to determine their dimensions and weight, as opposed to being machine-processed, require a non-machinable stamp. This is because these packages cannot pass through the standard automated machinery, necessitating manual inspection.
- Tubes and Cylinders: Items with a diameter or circumference that exceeds normal dimensions, requiring additional postage for processing
- Irregular Shapes: Packages with unusual or hard-to-measure shapes that cannot fit through automated scanners
- Packages with Protrusions: Items with protruding objects, flaps, or other features that hinder processing through machinery
Additional Postage for Non-Machinable Items
Items with non-machinable requirements often necessitate the use of additional postal labels or stamps, which can increase postage costs. The price of the additional postage depends on the type of non-machinable item, size, and weight.
| Item Type | Price Range for Additional Postage (USD) |
|---|---|
| Tubes and Cylinders (1 oz) | $2.75 – $8.75 |
| Irregular Shapes (1 oz) | $2.50 – $7.50 |
| Packages with Protrusions (1 oz) | $2.00 – $6.00 |
Preparation and Handling of Non-Machinable Stamps

Non-machinable stamps require special handling to prevent damage and ensure accurate postage calculations. When preparing and handling non-machinable stamps, it is essential to follow specific guidelines to avoid any errors or delays in mail processing.
Packaging and Handling of Non-Machinable Stamps
When packaging non-machinable stamps, consider the shape, size, and weight of the items. Non-machinable stamps often have irregular shapes or sizes, which can make them prone to damage during transit. Wrap each item individually in bubble mailers or use specialized packaging materials to prevent damage. Use sturdy boxes and fill any empty spaces with packing materials to prevent movement during shipping.
When handling non-machinable stamps, it is crucial to treat them with care to prevent damage. Use gloves when handling stamps, and avoid touching the adhesive side to prevent oils from your skin from affecting the glue. Store non-machinable stamps in a secure, dry location away from direct sunlight to prevent degradation.
Labeling and Tracking of Non-Machinable Stamps
Accurate labeling and tracking are essential for non-machinable stamps. Ensure that all packages containing non-machinable stamps are properly labeled with the correct postage, including the required non-machinable stamp. Consider using tracking and barcoding to ensure that packages are delivered to the correct destination.
Machinable vs. Non-Machinable Stamp Calculations
When calculating postage for non-machinable stamps, it is crucial to use the correct rates. Non-machinable stamps have specific postage rates, and mis-calculating postage can result in lost revenue or delayed mail processing. Consider using specialized postage software or consulting with a postage expert to ensure accurate calculations.
Specialized Equipment and Supplies for Non-Machinable Stamps
When working with non-machinable stamps, specialized equipment and supplies may be necessary to prevent damage and ensure accurate postage calculations. Consider investing in specialized postage scales, calculators, or packaging materials to ensure that your non-machinable stamps are handled and processed correctly.
USPS Regulations and Guidelines for Non-Machinable Stamps
USPS non-machinable stamps play a crucial role in mailing irregularly shaped packages and letters. The USPS has established specific regulations and guidelines for using non-machinable stamps. These guidelines ensure that packages are handled and processed efficiently while also providing a way for individuals to accurately calculate postage costs for unusual mail pieces.
Machinable Mail Definitions, Usps non machinable stamp
USPS defines machinable mail as packages that can be processed by automated machines. This includes packages with specific dimensions, weights, and shapes. To qualify as machinable mail, packages should have a rectangular shape with no odd-shaped protrusions. USPS considers packages with non-standard shapes, such as irregularly curved or angled sides, as non-machinable mail.
USPS Guidelines for Non-Machinable Stamps
The USPS has established the following guidelines for non-machinable stamps:
- Square or rectangular packages with one side longer than an inch (25.4 mm)
- Packages with a height-to-length ratio of 1.5 or greater (in any direction)
- Packages exceeding the weight limits for machinable mail (up to 70 lbs. for flat-rate packages and 70 lbs. for large envelopes)
- Odd-shaped protrusions or features that interfere with automated processing
- Packages made from non-standard materials, such as bubble mailers or padded envelopes
For packages that do not fit under the above categories, postage must be calculated separately.
Calculating Postage for Non-Machinable Mail
Using USPS Calculators
USPS provides free online tools to help calculate postage costs for non-machinable mail. These tools take into account factors such as the package’s weight, size, and destination zip code. This helps ensure accurate postage calculations and helps prevent mail delays due to insufficient postage.
Weight-Based Postage Rates
Non-machinable mail rates are based on the package’s weight, not its size or shape. To calculate the correct postage, multiply the package’s weight by the applicable rate per pound. This ensures that packages are charged based on their actual weight, not their dimensions.
Additional Considerations
When preparing packages for shipment, ensure that the non-machinable stamp is affixed to the package in a secure and visible location. If a package does not meet the guidelines for non-machinable mail, an additional fee may apply. Consult with a USPS representative or visit the USPS website for more information on non-machinable stamps and postage calculations.
