Miss. Code § 49-7-163
It is unlawful for any person sixteen (16) years of age or older to hunt or take any migratory waterfowl within this state without first procuring a state migratory waterfowl stamp or its electronic equivalent and having the stamp or proof of purchase of the electronic equivalent in his possession while hunting or taking any migratory waterfowl. Any penalty for not having the stamp in possession while engaged in hunting or taking migratory waterfowl shall be waived if the person can verify purchase of a stamp prior to the date of the violation. Each stamp shall be validated by the signature of the licensee written across the face of the stamp or the proof of purchase of the electronic equivalent. The commission shall determine the form of the stamp and the electronic equivalent and shall furnish the stamps to bonded agents for issuance or sale in the same manner as other types of licenses or cause the electronic equivalent to accrue to the purchaser's benefit when purchasing a license from an automated point of sale vendor.
