Hello, and welcome!
I'm sorry you forgot your combination; I know how frustrating this can be.
Combinations are not available online for your protection and security. The only way to retrieve your combination is from the manufacturer, Sentry. You can do that by going to the website below, and following all directions, including filling out a notary form, proving safe ownership.
Sentry is not open on the weekend, so you can submit your information now, and then, it will be processed on Monday. If this is urgent, but you can wait a couple of days, you can request 'expedited shipping' as you will see at the webpage above; this will enable you to retrieve your combination within 1-2 business days from when they process it.
If this is an emergency, your only alternative is to hire a local locksmith/safe technician to help open your safe without destroying it.
I wish I had better news for you, and I can really empathize, but this is Sentry's procedure for recovering lost combinations.
I hope my information helped and you can recover your combination as quickly as possible!
Please be so kind as to rate my answer with positive feedback; that is the only way I receive recognition from the site for my assistance. Thank you very much!
