Under the Penitentiary Act B.E. 2479 (1936), once a person is imposed to imprisonment, he/she shall be regarded as a prisoner and shall be subject to undergo these following admission procedures:


In order to inspect and identify items to be permitted or not to be permitted to bring into prison, each prisoner is subject to a body-search and searching of personal belongings.

      (1) Permitted items:

  • Sanitary items such as toothbrush, toothpaste, soap, towel, etc.
  • Cooked food as approved by the prison director.


Any items not mentioned above will be put into the prison director’s approval. The identification card or any electronic cards (ATM card) will be kept by prison authorities.


      (2) Un-permitted items:

  • Contrabands:

–    Narcotic drugs, inhalant substance

–    Alcohols or other similar liquors

–    Gambling materials

–    Tools for escape

–    Weapons, bullets, explosives, fire work, and weapon accessories

–    Perishable or toxic items

–    Fuel

–    Living animals

–    Computers, mobile phones and other electronic devices

–    Items or documents which can cause disorder or ethical conflicts

Before entering a prison, a prisoner has to hand or to sell away un-permitted items to his/her relatives or outsiders. If a prisoner cannot afford to do so, he/she shall have to deposit them with prison authorities or to frustrate them (in case of perishable or toxic items). Those who fail to comply shall be subject to criminal charge and disciplinary punishment.

  • Cash:

Cash will be deposited in a prisoner’s account called “Book”. A prisoner can withdraw in terms of card or coupon to buy things. The withdrawal amount per day must not exceed the amount ordered by the Department of Corrections otherwise; the prisoner has to make an official request and receive approval from the prison authority. The Department of Corrections has a regulation in which prisoners would not be allowed to have or use cash during their imprisonment. Any cash found inside any prison will be forfeited to the State and one who violates the regulation will receive both penalty and discipline punishment.

(3) Others   

Other items not described in (1) and (2), such as valuable accessories (necklace, ring, watch, small images of Buddha, etc.), are to be given to prisoner’s relatives or to be kept by the prison.


A prisoner is photographed, fingerprinted, and interviewed about his/her background in order to seek further assistance and to prevent a release mistake. The prisoner shall have to inform the 13-digit-identification number for issuing the National Health Assurance Card. If the prisoner has already got the National Health Insurance Card, he/she is required to show it so as to adjust the right of treatment.


Physical check-up is to be performed by a doctor or other medical staff on the admission date or on the following date.


In case a prisoner has a child/children attached to him/her, the child/children will be allowed to be with the prisoner in prison temporarily. A Child/children attached to the prisoner should not be over 3 years of age. In case the age of the child exceeds 3 years, he/she shall have to be taken outside prison to the custody of the relatives, or to the custody of public orphan facility.


In case a prisoner is pregnant when being sent into prison, after birth giving, the treatment procedure will be as the foregoing passage.


After the foregoing procedures, the prisoners will be sent to the admission centre for the following processes:

(1)    Orientation:

To introduce and explain prison rules and regulations that the prisoners have to conform to during their imprisonment, including the prisoner’s rights and privileges.  Drill exercise is performed as part of prison disciplinary training.

(2)    Classification:

Social workers or psychologists will conduct interviews to collect information of each prisoner. The gained information will be forwarded to the Prison Classification Committee. The prisoners may be brought to meet with the Committee in order to plan an appropriate treatment for each prisoner, such as education, vocational training, medical service, or social welfare assistances. If the information received from the interview is incorrect the prisoners may receive disadvantages or may lose certain privileges, such as rights of contact visit, medical welfare services, parole, and good-conduct allowances.
