Contact your lender as soon as possible.

Lenders who offer private student loans are offering assistance to borrowers who can’t make their loan payments during the coronavirus outbreak. However, they typically don’t reach out to make these options known to you. Instead, you need to contact them yourself.

If at all possible, reach out to your lender if you anticipate difficulty, before you actually have a problem. If you miss a payment, it will not only damage your credit score but also cost you additional interest and fees.
Typically you can call your lender’s toll-free customer service number for more information. However, since a lot of other people are in the same position as you are, you’re likely to have to wait on hold for a long time before you can talk to someone. Looking for information on your lender’s website will be more efficient.
