If your package requires a signature and you missed the delivery, the carrier will usually try to deliver the package again on the next business day.
Keep in mind that most carriers don’t deliver on Sundays. So if your first delivery attempt was on a Saturday, the next delivery attempt would typically happen on Monday.
If it may be challenging to have someone present to sign for your package, consider contacting the carrier to request that they hold your package at a local facility for pickup.
