Envelopes for office and personal use come in many different shapes and sizes. For many businesses, envelopes play an integral role in daily operations. They are used for return mail and to relay sensitive information securely. Size 9 or #9 envelopes are heavily relied upon by businesses because they fit easily inside of the larger #10 envelopes (4 1/8" x 9 ½”). These envelopes are the perfect choice for receiving return mail, like payments, donations and other reply mail. Read on to learn more about why you should consider including size 9 envelopes on your next order of office supplies.

What Are Size 9 Envelopes Used For?

Size 9 envelopes fit perfectly in their larger counterparts, #10 envelopes, making them perfect for return or reply mail. Businesses that send messages that require a reply or return mail on behalf of the recipient will typically use the #9 envelope size. Credit card companies, insurance firms and non-profits often include these envelopes in their messages to make it easier for the recipient to mail a payment or donation. Magazines may send out size 9 envelopes with their latest issue if it's time to subscribe again.

What Features Do Size 9 Envelopes Have?

Depending on what a business’ needs are, there are many different size 9 envelopes to choose from. Staples offers a range of color and design options for businesses who are looking to put a personal touch on their correspondence with clients. Some #9 envelopes even come with security features such as tinted plastic films to ensure that a customer’s sensitive information is secure in transit. Read more about these common size 9 envelope features below.

Tinted Security Windows

Many size 9 envelopes designed for sending documents that contain sensitive information feature tinted security windows. A business might provide customers with tinted envelopes because they offer a means of theft deterrent. #9 envelopes with a security tint are a good option for debt collectors and non-profits alike because people are less likely to tamper with an envelope if they do not suspect there’s money involved. For many companies, this is a best practice to incorporate, because it ensures that there are no hiccups while requesting payments or sensitive information through the mail.

Strong Adhesive Seals

Staples offers a variety of size 9 envelopes and seal options. The most commonly used style is a traditional gum seal. Gum seal envelopes have a water-soluble gum strip that you moisten to seal. Many modern size 9 envelopes have adhesive strip seals for those who require an added layer of security. Self-seal and moistenable glue #9 envelopes come with a strong adhesive that’s ready to peel and go. These built-in seals are similar to shipping and packing tape and erase any fears one might have about their mail opening in transit.

Many Colorful Options to Choose From

The #9 envelope size comes in many colors for professionals and businesses that want to add a more personal or creative touch to their correspondence with customers. At Staples, you can choose from orange, pink, beige and everything in between. These fun size 9 envelope shades help add a personal touch to any business’ marketing campaigns - a perfect choice to consider when the time comes for customers to resubscribe!
