Interfolio will check the following items when QC'ing letters:

  • If the letter has a signature
    • Physical Signature
    • Digital Signature
  • If the letter is on official letterhead
    • Includes logo/seal

Types of Signatures that Interfolio Identifies through the QC process:

Interfolio understands that signatures are in most cases a requirement.  Along with informing you whether one exist, we will also let you know what type of signature is on your letter.  Keep in mind that most institutions, fellowship programs, and various other opportunities may require the traditional handwritten signature.  If by chance your letter includes another type of sigmature, or no signature at all---it is your responsibility to get in contact with the letter writer/evaluator in order to get that letter updated with the proper formatting.


Handwritten Signature

Handwritten signatures are pretty self explanatory--the letter writer/evaluator has put pen to paper and wrote their signature on the letter.  Because the signature is written in by the letter writer, you may get questions on how to submit this letter.  If you choose to have your letter writer submit their letter electronically, the letter writer will need to have the ability to scan their document to a computer, save it, and then submit it through the emailed request they receive.  Letter writers can also mail their letter to Interfolio if you choose the "printed form" option of delivery in the letter request form.  Below are examples of a handwritten signature:


signature (/ˈsɪɡnətʃər/; from Latin: signare, "to sign") is a handwritten (and often stylized) depiction of someone's name, nickname, or even a simple "X" or other mark that a person writes on documents as a proof of identity and intent.

The point is the handwritten signature has to be written on the document by the signer.


Digital Signature

The digital signature is simply a small block of data that is attached to documents you sign. It is generated from your digital ID, which includes both a private and public key. The private key is used to apply the signature to the document, while the public key is sent with the file. Digital signatures usually include a mark or stamp to authenticate it.  

Most organizations will accept a digital signature in place of a handwritten one.

Here are a few examples below:

A digital signature is a type of electronic signature that encrypts documents with digital codes that are particularly difficult to duplicate.

No Signature

 Some examples of what we would consider a document without a signature to look like are:


When the writer typed their name in the signature block and changed the font to a more stylized type font, or does not include anything in the signature block.  These are not considered a signature.  

When will Interfolio Quality Check?

Quality Check Time: 4 business days

A confidential letter of recommendation enters the QC process in two ways:

  1. If the recipient has a free Dossier account, then the letter will be QC'd when it is used in a delivery, or when they upgrade to a premium account.
  2. If the recipient has a premium Dossier Deliver account, then the letter enters the QC process immediately upon receipt, or when they have upgraded.
