I believe that the OP means: Identifying Ordinary and Universal Magisterium of the Catholic Church. I can understand some confusion on this topic as the terms in use are in no way constant and even are somewhat changeable. The Church has yet to update its' canonical language on this subject.
The term ‘ordinary magisterium’ was first used by Pius IX in the letter Tuas libenter addressed to the archbishop of Munich and Freising on 21 December 1863.
Earlier that year, a meeting of Catholic theologians had taken place in Munich. The pope had been told that in the course of that meeting the opinion had been expressed that Catholic theologians were bound to hold only those truths of faith which had been solemnly declared.
Pius IX replied that “it must not be limited to those things which have been defined by the express decrees of councils or of the Roman Pontiffs and of this Apostolic See, but must also be extended to those things which are handed on by the ordinary magisterium of the whole church dispersed throughout the world as divinely revealed, and therefore are held by the universal and constant consensus of Catholic theologians to pertain to the faith.”
Pius IX to Vatican II
The teaching of Pius IX on ordinary magisterium was later incorporated in the documents of Vatican I, in particular the dogmatic constitution Dei Filius: “Wherefore, by divine and catholic faith all those things are to be believed which are contained in the word of God as found in scripture and tradition, and which are proposed by the church as matters to be believed as divinely revealed, whether by her solemn judgment or in her ordinary and universal magisterium.”
It was understood that the addition of ‘universal’ to ‘ordinary magisterium’ was meant to relate the phrase to the teaching of the whole episcopate with the pope, and not the teaching of the pope alone.
Further clarifications
When the Code of Canon Law was promulgated in 1983, the ordinary and universal magisterium was dealt with in canons 749 and 750, but without the inclusion of the broader understanding of the ordinary universal magisterium by Vatican II.
In other words, the canonical language had not been updated yet. - “What is the ‘ordinary magisterium’? A brief history of a disputed idea
